This is a helper class for the AttributeSetImpl class. It holds a set of
attributes that apply to a single element: function, return type, or
parameter.
These are uniqued.

The global module index is a "global" index for all of the module
files within a particular subdirectory in the module cache, which
keeps track of all of the "interesting" identifiers and selectors
known in each of the module files. One can perform a fast lookup in
the index to determine which module files will have more information
about entities with a particular name/selector. This information can
help eliminate redundant lookups into module files (a serious
performance problem) and help with creating auto-import/auto-include
Fix-Its.
The global module index is created or updated at the end of a
translation unit that has triggered a (re)build of a module by
scraping all of the .pcm files out of the module cache subdirectory,
so it catches everything. As with module rebuilds, we use the file
system's atomicity to synchronize.

GCC implements -Wvla as "warn on every VLA" (this is useful to find every VLA,
for example, if they are forbidden by coding guidelines). Currently Clang
implements -Wvla as "warn on VLA when it is an extension".
The attached patch makes our behavior match GCC. The existing vla extwarn is
moved under -Wvla-extension and is still included into -Wgnu.
This fixes PR5953.

identifiers into two parts: the part that involves dealing with the
key (which can be re-used) and the ASTReader-specific part that
creates the IdentifierInfos. While I'm at it, StringRef'ify this code,
which was using pair<const char*, unsigned>. No functionality change.

Proper reconstruction of the macro info history from modules will properly fix this in subsequent commits.

Before:
int aaaa = aaaaa().aaaaa() // force break
.aaaaa();
After:
int aaaa = aaaaa().aaaaa() // force break
.aaaaa();
The other indent is just wrong and confusing.
llvm-svn: 173273
Before:
bool aaaa = aaaaaaaaaaa(
aaaaaaaaaaaaaaaaa);
After:
bool aaaa = aaaaaaaaaaa(
aaaaaaaaaaaaaaaaa);
The other indentation was a nice attempt but doesn't work in many cases.
Not sure what the right long term solution is as the "After: " is still
not nice. We either need to figure out what to do in the cases where it
"doesn't work" or come up with a third solution, e.g. falling back to:
bool aaaa =
aaaaaaaaaaa(
aaaaaaaaaaaaaaaaa);
which should always work and nicely highlight the structure.

This is still an egregious hack since we don't have a nice interface for this
