* Elfin will eventually get into a state where it ignores coins.
Protection is conceptually similar to The X-Files.
-cpu/uml.cpp, cpu/drcuml.cpp: Made it possible to build with logging
simplifications enabled (in uml.cpp it logs each step, in drcuml.cpp it
logs the net change). It will produce absoluely massive logs, though.
-cpu/drcuml.cpp: Removed woefully inadequate and badly rotted "backend
validation" code.

recompiler issues:
* cpu/drcbearm64.cpp Interpret index operand for load and store
instructions as a signed 32-bit value for consistency with x86-64.
Moved code to interpret load and scale the index for integer
load/store to a helper function to make it easier to update if it
needs changes or fixes.
* cpu/drcbearm64.cpp: Use and/orr to set carry flag directly rahter than
using an intermediate register when both operands of a CARRY
instruction are immediates.
* cpu/drcbearm64.cpp: Fixed incorrect operand type assertion for FREAD.
* cpu/drcbearm64.cpp: Use less verbose asmjit helper functions for shift
operations and addressing modes.
* cpu/drcbex64.cpp: Interpret index operand for floating point
load/store as a signed 32-bit value for consistency with integer
load/store.
* cpu/drcbex64.cpp: Guard against any possibility of load and store
instructions altering the flags.
* cpu/drcbex64.cpp: Reduced copy/paste in floating point load/store
instructions.
* cpu/drcbex64.cpp: Cleaned up some casts between integer types with
differing size and signedness.
* docs: Added reference for UML flow control, data movement and emulated
memory access instructions.
* cpu/uml.cpp: Truncate immediates to size for a few more instructions.
* cpu/uml.cpp: Added SPACE_OPCODES since it's a well-known address space
now.
* cpu/uml.cpp: Removed SCALE_DEFAULT. It's unimplemented by back-ends
and unused by front-ends.
* cpu/uml.h, cpu/drcumlsh.h: Less confusing names for parameters to read
and write instruction generators.
* cpu/drcbex86.cpp: Templated 64-bit multiplication helpers on the
zero/sign flag source, cleaned up casting pointers to integers.

* cpu/uml.cpp: Fixed some cases where simplifying multiplication
instructons incorrectly changed output flags.
* cpu/drcbex64.cpp: Fixed some cases where a ROLC/RORC with zero shift
count could incorrectly clear the carry flag.
* cpu/drcbex86.cpp: Made 64-bit ROLC/RORC with zero bit count preserve
the carry flag.
* cpu/drcbec.cpp: Fixed FSMOV/FDMOV turning things that look like
signalling NaNs into quiet NaNs on i686.
* cpu/drcbex64.cpp: Greatly reduced copy/paste in the code generation
for multiply instructions.

* Also added a few more simplifications.
* cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Removed more speical cases for
things the simplifier deals with.

* Fixed many cases that could cause the upper bits of a register not to
cleared following a 32-bit operation.
* Added more simplifications.
* Allow many simplifications when flag updates are requested.
* Fixed various bits of unreachable code.
* cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Removed code for special-casing
some situations the simplifier can now take care of consistently.
-cpu/drcbex64.cpp: Fixed a bug causing some shifts to be treated as a
no-op when the destination and source are not the same.
-cpu/drcbearm64.cpp, cpu/drcbex64.cpp: Added a special case for
comparing something to itself.
-cpu/e132xs: Use the CARRY instruction rather than a right shift to set
up carry in.

* cpu/uml.cpp: Handle some more cases where ROLAND can be turned into
AND in the simplifier.
* cpu/drcbearm.cpp, cpu/drcbex64.cpp: Fixed a number of cases where
4-byte operations wouldn't clear the upper half of the destination
(there are plenty more of these caused by the simplifier that will be
harder to fix).
* cpu/drcbearm64.cpp: Fixed some cases where a conditional MOV could
unexpectedly clear the upper bits of the destination.
* cpu/drcbex64.cpp: Improved code generation for various arithmetic and
logical operations. More AND/OR/XOR/ADD/ADDC operand combinations are
optimised. Special cases of ROLAND/ROLINS are optimised.
* cpu/drcbex64.cpp: Don't treat operands to FADD/FMUL as commutative.
This isn't true when one is a NaN.
-cpu/e132xs: Use osd_printf_error for diagnositc output, and make more
local variables const.

* cpu/uml.cpp: Removed unused vector type.
* 3rdparty/asmjit: Update asmjit to latest upstream.
* cpu/drcbex64.cpp: Fixed crash with LOG_HASHJMPS enabled (stack needs to be 16-byte aligned before calling debug_log_hashjmp_fail).

* cpu/drcbex86.cpp: Clear top half of iregs on loads to I0-I3, fix LOADS sign extension, and fixed FLOAD/FSTORE data size.
* cpu/drcbex64.cpp: Use appropriate register size for LOAD.
* cpu/drcbec.cpp: Fix parameter sizes for READM/WRITEM, and clear upper half of registers after 32-bit operations.
* cpu/uml.cpp: Fixed definition for FSREAD/FSWRITE and FDREAD/FDWRITE, and fixed READM/WRITEM simplification.

* cpu/drcbec.cpp: Added more methods of accessing OP_CARRY.
* cpu/drcbec.cpp: Fixed flag calculation for BSWAP and MULS opcodes.
* cpu/drcbec.cpp: Made calculation for shift and rotation opcodes consistent.
* cpu/drcbec.cpp: Return mapvar register ID instead of value for mapvars.
* cpu/drcbex64.cpp, cpu/drcbex86.cpp: Fixed bugs in various opcodes to make them behave like the C backend.
* cpu/drcbex64.cpp: Fixed SAVE, RESTORE and SETFMOD.
* cpu/powerpc: Implement MULLWx and MULLWOx using the new MULSLW opcode.

- Add mul_16x16 inline function to perform a signed 16x16-bit multiplication with 32-bit result. This was moved from cpu/e132xs to unite it with the analogous 32x32 operations.
- Add rotl_32, rotr_32, rotl_64 and rotr_64 inline functions to perform 32-bit and 64-bit circular shifts in either direction by the specified number of places, modulo 32 or 64. It is anticipated that these will eventually be replaced by standard functions in C++20's <bit> header, and so they have been given similar signatures and semantics (which are also validity-checked).
- Remove LSL, LSR, ROL and ROR macros from cpu/arm and cpu/arm7 to ameliorate unnecessary obfuscation.

(nw) This has been a long time coming but it's here at last. It should
be easier now that logerror, popmessage and osd_printf_* behave like
string_format and stream_format. Remember the differences from printf:
* Any object with a stream out operator works with %s
* %d, %i, %o, %x, %X, etc. work out the size by magic
* No sign extending promotion to int for short/char
* No widening/narrowing conversions for characters/strings
* Same rules on all platforms, insulated from C runtime library
* No format warnings from compiler
* Assert in debug builds if number of arguments doesn't match format
(nw) Also removed a pile of redundant c_str and string_format, and some
workarounds for not being able to portably format 64-bit integers or
long long.

- strprintf is unaltered, but strformat now takes one fewer argument
- state_string_export still fills a buffer, but has been made const
- get_default_card_software now takes no arguments but returns a string
