GCC applies a pragma weak to a decl if it matches the mangled name. We used
to apply if it matched the plain name.
This patch is a compromise: we apply the pragma only if it matches the name
and the decl has C language linkage.

Empty lines followed by line comments are often used to highlight the
comment. Empty lines somewhere else are usually left over from manual or
automatic formatting and should probably be removed.
Before (clang-format would keep):
S s = {
a,
b
};
After:
S s = { a, b };
llvm-svn: 176086
We might want to move towards doing this if the formatting can be
significantly improved, but we need to carefully evaluate the different
situations first.
Before (the string literal was split by clang-format here):
aaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaa, aaaaaa("aaa aaaaa aaa aaa aaaaa aaa "
"aaaaa aaa aaa aaaaaa"));
After:
aaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaa,
aaaaaa("aaa aaaaa aaa aaa aaaaa aaa aaaaa aaa aaa aaaaaa"));

These are two related changes (one in llvm, one in clang).
LLVM:
- rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode)
- rename thread_safety => sanitize_thread
- rename no_uninitialized_checks -> sanitize_memory
CLANG:
- add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis))
- add __attribute__((no_sanitize_thread))
- add __attribute__((no_sanitize_memory))
for S in address thread memory
If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not
set llvm attribute sanitize_S

Fix a bug where if two atoms had the same index in the override map,
the compare would return false. It now goes to the next check when
they are equal.
No test because it currently can't be tested. An upcomming patch will test it.

Normally, we need to look through derived-to-base casts when creating
temporary object regions (added in r175854). However, if the temporary
is a pointer (rather than a struct/class instance), we need to /preserve/
the base casts that have been applied.
This also ensures that we really do create a new temporary region when
we need to: MaterializeTemporaryExpr and lvalue CXXDefaultArgExprs.
Fixes PR15342, although the test case doesn't include the crash because
I couldn't isolate it.
llvm-svn: 176069
With the new support for trivial copy constructors, we are not always
consistent about whether a CXXTempObjectRegion gets reused or created
from scratch, which affects whether qualifiers are preserved. However,
we probably don't care anyway.
This also switches to using the current PrintingPolicy for the type,
which means C++ types don't get a spurious 'struct' prefix anymore.

SymbolFileDWARF code:
- If a class is being uniqued to another copy of itself
and the method lists don't match exactly, take a slow
path and at least unique the methods that they have
in common.
- Sort name_to_die maps before querying them. This
would otherwise result in uniquing failures because
looking up a name in a map that contains it would
often fail.
- Tolerate classes in other symbol files in the case
of debugging with .o files rather than with a
.dSYM. We used to assume that the classes being
uniqued were in the same symbol file, causing
unpredictable results.
This will dramatically reduce the number of cases where
a function does not have a valid DeclContext.

Remove the getCategory from TestDataFormatterObjC.py, since it was superceded by the .categories file,
