Convert 2-byte opcodes to equivalent 1-byte ones. Adjust the existing exhaustive testcase to avoid being altered by the simplification rules (to keep that test exercising all individual opcodes). Fix the assembler parser limits for register pairs; for .seh_save_regp and .seh_save_regp_x, we can allow up to x29, for a x29+x30 pair (which gets remapped to the UOP_SaveFPLR(X) opcodes), for .seh_save_fregp and .seh_save_fregpx, allow up to d14+d15. Not creating .seh_save_next for float register pairs, as the actual unwinder implementation in current versions of Windows is buggy for that case. This gives a minimal but measurable size reduction. (For a 6.5 MB DLL with 300 KB .xdata, the .xdata shrinks by 48 bytes. The opcode sequences are padded to a 4 byte boundary, so very small improvements might not end up mattering directly.)
