lit.cfg: Don't expand %ms_abi_triple to non-X86 triples

This is a follow-up to r199260. On ARM hosts, we were attempting to run
tests with triples such as armv7l-unknown-win32. This expands that fix to
cover all non-x86 targets since we only support MS ABI on x86.

Rename QA_OVERRIDE_GCC3_OPTIONS to CCC_OVERRIDE_OPTIONS. <rdar://14578381>

for people who rely on this.

Fixed error recovery if sizeof is used without parenthesis

Changes made in r192200 fixed PR16992, which requested fixit suggesting
parenthesis if sizeof is followed by type-id. However expression in form
T() followed by ')' was incorrectly considered as a type-id if 'T' is
typedef name. This change fixes this case.
