In real x86 processors, the REX prefix must come after legacy prefixes.
REX before legacy is ignored. Update the HVF emulation code to properly
handle this. Fix some spelling errors in constants. Fix some decoder
table initialization issues found by Coverity.

We commonly define the header guard symbol without an explicit value.
Normalize the exceptions.

According to Intel(R)64 and IA-32 Architectures Software Developer's
Manual, the following one-byte registers should be fetched when REX
prefix is present (sorted by reg encoding index):
AL, CL, DL, BL, SPL, BPL, SIL, DIL, R8L - R15L
The first 8 are fetched if REX.R is zero, the last 8 if non-zero.
The following registers should be fetched for instructions without REX
prefix (also sorted by reg encoding index):
AL, CL, DL, BL, AH, CH, DH, BH
Current emulation code doesn't handle accesses to SPL, BPL, SIL, DIL
when REX is present, thefore an instruction 40883e "mov %dil,(%rsi)" is
decoded as "mov %bh,(%rsi)".
That caused an infinite loop in vp_reset:
