eminline.h: Additions
- 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.
