Dmitri Gribenko ef099dc670 Comment parsing: attach comments to enums declared using the NS_ENUM macro 
Previously we would only attach comments to the typedef.

Dmitri Gribenko 9ee0e303d6 Comment parsing: when comment ranges are deserialized from multiple modules, 
correctly order comments in SourceManager::isBeforeInTranslationUnit() order

Unfortunately, this is not as simple as it was implemented previously, and
actually requires doing a merge sort.

Richard Smith a8b7459115 If a DeclContext's lookups need to be reconciled, and we're given external declarations for a name, reconcile first. Otherwise, when we come to reconcile, we'll ask for external declarations for that name again. No functionality change intended.

David Majnemer 58e5bee17a MS ABI: Eliminate Duplicate Strings 
COFF doesn't have mergeable sections so LLVM/clang's normal tactics for
string deduplication will not have any effect.

To remedy this we place each string inside it's own section and mark
the section as IMAGE_COMDAT_SELECT_ANY.  However, we can only do this if the
string has an external name that we can generate from it's contents.

To be compatible with MSVC, we must use their scheme.  Otherwise identical
strings in translation units from clang may not be deduplicated with
translation units in MSVC.

This fixes PR18248.

N.B. We will not attempt to do anything with a string literal which is not of
type 'char' or 'wchar_t' because their compiler does not support unicode
string literals as of this date.  Further, we avoid doing this if
either -fwritable-strings or -fsanitize=address are present.

This reverts commit r204596.

David Majnemer 96bc4b0367 MS ABI: Add tests, other cleanups for r204562 
This commit cleans up a few accidents:
- Do not rely on the order in which StringLiteral lays out bytes.
- Use a more efficient mechanism for handling so-called
  "special-mappings" when mangling string literals.
- There is no need to allocate a copy of the mangled name.
- Add the test written for r204562.

Thanks to Richard Smith for pointing these out!

Yunzhong Gao fcdc45ff2d Creating a printing policy for "half": 
Since "half" is an OpenCL keyword and clang accepts __fp16 as an extension for
other languages, error messages and metadata (and hence debug info) should refer
to the half-precision floating point as "__fp16" instead of "half" when
compiling for non-OpenCL languages. This patch creates a new printing policy for
half in a similar manner to what is done for bool and wchar_t.
