L'x' is actually wchar_t

support C11 u and U char literals

llvm-svn: 148390

Updates ProcessUCNExcape() for C++. C++11 allows UCNs in character
and string literals that represent control characters and basic
source characters. Also C++03 allows UCNs that refer to surrogate
codepoints.

UTF-8 sequences in character literals are now handled as single
c-chars.

Added error for multiple characters in Unicode character literals.

Added errors for when a the execution charset encoding of a c-char
cannot be represented as a single code unit in the associated
character type. Note that for the purposes of this error the asso-
ciated character type for a narrow character literal is char, not
int, even though in C narrow character literals have type int.

Implement AsanProcMaps for Mac OS. The code from sysinfo/ is not needed anymore and should be cleaned up.

Fix a bug in the type-legalization of vector integers. When we bitcast one vector type to another, we must not bitcast the result if one type is widened while the other is promoted.

No new unit tests yet as there is no behavioral change
(except for slightly more specific filtering in
Sema::ActOnStartOfLambdaDefinition). Tests will be added
as the code paths are traced in greater depth to determine
how to improve the results--there are at least one or two
known bugs that require those improvements. This commit
lays the groundwork for those changes.

for it to be used in converted constant expression checking, and fix a couple
of issues:
 - Conversion operators implicitly invoked prior to the narrowing conversion
   were not being correctly handled when determining whether a constant value
   was narrowed.
 - For conversions from floating-point to integral types, the diagnostic text
   incorrectly always claimed that the source expression was not a constant
   expression.

Add a '-X excluded-dir' option to the test driver to exclude a directory from consideration during test discovery.  For example:

    ./dotest.py -X types -v

from the test dir will ignore test cases under test/types.

Load/store instructions w/ a fixup to be relative a function marked as thumb
don't use the low bit to specify thumb vs. non-thumb like interworking

When set, this bit indicates that a register is completely defined by
the value of its sub-registers.

Use the CoveredBySubRegs property to infer which super-registers are
call-preserved given a list of callee-saved registers.  For example, the
ARM registers D8-D15 are callee-saved.  This now automatically implies
that Q4-Q7 are call-preserved.

Conversely, Win64 callees save XMM6-XMM15, but the corresponding
YMM6-YMM15 registers are not call-preserved because they are not fully
defined by their sub-registers.
