Macros frequently contain extra '()' to make instantiation less error prone.
This warning was flagging a ton of times on postgresql because of its use of macros.

This is completely untested but pretty straightforward, so hopefully I
got it right.

BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").

This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

[AVX] Implement EnforceSmallerThan for mixed int/fp type lists.  This
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

It's highly likely that the user intended an assignment used as condition.

Add temporary hack to -Wuninitialize to create a separate CFG (for C++ code) that doesn't include implicit dtors.

Implicit dtors confuse the ad hoc path-sensitivity of UninitializedValuesV2.cpp.  This isn't
the ideal solution, as it will directly impact compile time, but should significantly reduce
the noise of -Wuninitialized on some code bases.

This immediately "fixes" the false positive reported in PR 9063, although this
isn't the right fix in the long run.

llvm-svn: 124667

Enhance -Wuninitialized to better reason about || and &&, tracking dual dataflow facts and properly merging them.

Fixes PR 9076.
