Switch some things to use range-based for loops.
Change CXXUuidofExpr::GetUuidAttrOfType's return type to be const.
No functionality changed.

Prospectively revert to get one of the many build configurations back working
(presumably the side-by-side+modular CMake config).
This reverts commit r212997.

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.

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
would be diagnosed if typo correction suggests a replacement).

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.

The underlying function. utohex_buffer, already supports an argument for
deciding if the hex characters should be upper or lower case. Expose an
identical argument for utohexstr.

The attempt in r212980 was broken because we might not fail if
LLVM_ON_UNIX is enabled for cross compiling to Windows, and it didn't
consider mingw either.

Until now, attempting to create an alias of a required option would
complain if the user supplied the alias, because the required option
didn't have a value. Similarly, if you said the alias was required,
then using the base option would complain that the alias wasn't
supplied. Lastly, if you put required on both, *neither* option would
work.
By changning alias to overload addOccurrence and setting cl::Required
on the original option, we can get this to behave in a more useful
way. I've also added a test and updated a user that was getting this
wrong.

corresponding AST context function, only restricted to basic integer
types. Use this to ensure getUIntPtrType() gives types consistent with
getIntPtrType(). Fix NVPTX backend to give signed intptr_t.

Determining the bounds of x/ -1 would start off with us dividing it by
INT_MIN. Suffice to say, this would not work very well.
Instead, handle it upfront by checking for -1 and mapping it to the
range: [INT_MIN + 1, INT_MAX. This means that the result of our
division can be any value other than INT_MIN.

array prvalue), treat that as a direct binding. Only the class prvalue case
needs to be excluded here; the rest are extensions anyway, so we can treat them
as we would in C++11.

Summary:
When calculating the upper bound of X / -8589934592, we would perform
the following calculation: Floor[INT_MAX / 8589934592]
However, flooring the result would make us wrongly come to the
conclusion that 1073741824 was not in the set of possible values.
Instead, use the ceiling of the result.

Just because we can open a directory named "COcoa.framework" doesn't
mean we should provide a "COcoa" module on a case-insensitive filesystem.

We don't have a style guide for diagnostic messages, but convention strongly
favours the forms:
'attribute is not supported', 'unsupported attribute'
We generally avoid:
'attribute is unsupported', 'non-supported attribute'

This reverts commit r212957. It broke the self-host on code like this
from LLVM's option library:

Use -Winvalid-command-line-argument here to align with existing gcc opt
diagnostics. Meanwhile -Wunused-command-line-argument is for flags that we
support but were, say, fed into the wrong invocation.
Also tweak wording to make sense with -Werror.

The cmake files for libc++abi and the unwinder weren't linking against
libpthread or an unwind library. If the tests were linked with
-Wl,--as-needed, these libraries wouldn't be linked, causing them to
fail.
