H. Peter Anvin (Intel) 35016d4880 x86/insns.pl, tools/testgen: share cc/scc condition-code tables ...

Extract the condition-code suffix table (%conds, @conds, and the
c_ccmask/c_nd/c_cc/c_scc bitmasks) out of x86/insns.pl's
conditional_forms() into a new shared x86/insns-cc.ph module, adding
cc_suffix_list($is_scc) to return the suffix list applicable to a
'...cc'-family (Jcc, SETcc, CMOVcc, CFCMOVcc) or '...scc'-family
(CCMPscc, CTESTscc, CMPccXADD, SETccZU) placeholder mnemonic. insns.pl
is refactored to use it (behavior-preserving: verified byte-identical
x86/insnsa.c, insnsb.c, insnsd.c, insnsi.h, insnsn.c, iflag.c,
iflaggen.h, asm/tokhash.c, asm/tokens.h before/after).

tools/testgen/gen-insn-tests.pl now requires the same module instead
of hand-rolling a 16-suffix 'cc'-only expansion table, closing the gap
where the APX 'scc'-suffix families (CCMPscc/CTESTscc/CMPccXADD/
SETccZU) were dropped as unsupported. The generator now detects and
expands any '...cc'/'...scc' placeholder mnemonic the same way
insns.pl's conditional_forms() does (case-sensitive /s?cc/ match and
substitution), so future new cc/scc families need no generator
changes. Mnemonics with generated tests: 2432 -> 2606 (+174, one per
newly-expanded scc-family condition); dropped: 20 -> 16.

Regenerated travis/insns/ (174 new mnemonic dirs for the APX scc
families; existing 2432 regenerated byte-identically, confirming
determinism). Full suite validated both via
tools/travis/nasm-t.py --directory=./travis run (4427 total, 4426
PASS, 1 pre-existing SKIP, 0 FAIL) and via make -j32 travis (all
tests PASS, ~28s).
