Support APX CCMP and CTEST
CCMP and CTEST are two new sets of instructions for conditional CMP
and TEST, SCC and OSZC flags are given as suffixes of CCMP or CTEST
in the instruction mnemonic, e.g.:
ccmp<cc> { dfv=sf , cf , of } %eax, %ecx
also add
{evex} cmp/test %eax, %ecx
as an alias for ccmpt.
For the encoder part, add function check_Scc_OszcOperation to parse
'{ dfv=of , sf, sf, cf}', store scc in the lower 4 bits of base_opcode,
and adjust base_opcode to its normal meaning in install_template.
For the decoder part, add 'SC' and 'DF' macros to add scc and oszc flags
suffixes.
