96e513c8ea breaking! instrs: Decode VMOVS[SD] loads correctly
These instruction ignore the VEX operand if the source operand is a
memory location.

API compatibility: separate handling for different operand types in the
second and third operand (REG+REG vs. MEM+NONE) is needed.

a81582cc3a breaking! instrs: Decode MOVLHPS/MOVHLPS
Now that we support different /r and /m encodings on the same opcode, we
can easily identify MOVLHPS/MOVHLPS as different instructions.

API compatibility: existing code can point the new MOVLHPS/MOVHLPS
mnemonics to the existing handler for MOVHPS/MOVLPS.

db183ee6f9 meson: Check compiler options and Python version
Thanks to William Woodruff for pointing out that -Wcast-align=strict is
a GCC-only option, which causes build errors (instead of just
complaining about an unsupported warning option).

5a77c0e6eb parseinstrs: Use suffix tree to reduce mnem size
This brings slight size improvements, although due to SSE/MMX
instruction name prefixes, benefits are rather small (~50 bytes).
