tcg/x86_64: Avoid unnecessary REX.B prefixes.
The existing P_REXB internal opcode flag unconditionally emitsthe REX prefix. Technically it's not needed if the register inquestion is %al, %bl, %cl, %dl.
Eliding the prefix requires splitting the P_REXB flag into two,...
tcg/x86_64: Special-case all 32-bit AND operands.
This avoids an unnecessary REX.W prefix when dealing with ANDoperands that fit into a 32-bit quantity. The most common changeactually seen is movz[wb]q -> movz[wb]l.
Similarly, avoid REXW in ext{8,16}u_i64 tcg opcodes....
