AST: Fix __uuidof for template specializations
While we previously supported __uuidof applied to a template
specialization, we would only find the uuid attribute if it was applied
to the template argument. We would erroneously ignore the uuid
attribute on the specialization itself.
This is required to parse Windows Runtime C++ Template Library headers.

[X86] Specify all TSFlags bit-offsets symbolically
No functional change.
The offsets for the other bitfields are specified symbolically. I need to
increase the size for one of the earlier fields which is easier after this
cleanup.
Why these bits are relative to VEXShift is a bit strange but that is for
another cleanup.
I made sure that the values for the enums are unchanged after this change.

CodeGen: Stick constant pool entries in COMDAT sections for WinCOFF
COFF lacks a feature that other object file formats support: mergeable
sections.
To work around this, MSVC sticks constant pool entries in special COMDAT
sections so that each constant is in it's own section. This permits
unused constants to be dropped and it also allows duplicate constants in
different translation units to get merged together.
This fixes PR20262.

Continue parsing an expression list even after an error is encountered.
Otherwise, multiple errors such as having unknown identifiers for two
arguments won't be diagnosed properly (e.g. only the first one would
have a diagnostic message if typo correction fails even though both

[DAGCombiner] Add more rules to combine shuffle vector dag nodes.
This patch teaches the DAGCombiner how to fold a pair of shuffles
according to rules:
1. shuffle(shuffle A, B, M0), B, M1) -> shuffle(A, B, M2)
2. shuffle(shuffle A, B, M0), A, M1) -> shuffle(A, B, M3)
The new rules would only trigger if the resulting shuffle has legal type and
legal mask.
Added test 'combine-vec-shuffle-3.ll' to verify that DAGCombiner correctly
folds shuffles on x86 when the resulting mask is legal. Also added some negative
cases to verify that we avoid introducing illegal shuffles.
