Argyrios Kyrtzidis 61a3896d9f [PCH] We don't need to instantiate HeaderFileInfoTrait in ASTReader more than once.
We can just re-use the one from HeaderFileInfoLookupTable.

Shuxin Yang 408bdad5b4 Memory Dependence Analysis (not mem-dep test) take advantage of "invariant.load" metadata.
The "invariant.load" metadata indicates the memory unit being accessed is immutable.
A load annotated with this metadata can be moved across any store.

As I am not sure if it is legal to move such loads across barrier/fence, this
change dose not allow such transformation.

Edwin Vane 0a4836ed0e New ASTMatchers and enhancement to hasOverloadedOperatorName
Added two new narrowing matchers:
* hasMethod: aplies a matcher to a CXXRecordDecl's methods until a match is made
  or there are no more methods.
* hasCanonicalType: applies a matcher to a QualType's canonicalType.

Enhanced hasOverloadedOperatorName to work on CXXMethodDecl as well as
CXXOperatorCallExpr.

Updated tests and docs.

Stefanus Du Toit 49fe6388b6 Test case for PR-15414 - nullptr_t functions
The use-null-ptr transform will transform calls to functions that return a
nullptr_t. Even if the function were to only return a null pointer and do
nothing else, this replacement would still be undesired as the behavior and
signature of the function could change in the future.

This adds an XFAILed test case to demonstrate the issue.

Edwin Vane 105963d17c Fixed Use-Nullptr when replacing return(0)
Before fix, the paren expression was being replaced resulting in returnnullptr.
ParenExpr and implicit casts now ignored so we get return(nullptr) instead.

Greg Clayton 5d14fc061f Fixed enum printing for negative enums. There previously was no testing to validate that enum values were being displayed correctly.
Also added C++11 enum test cases to cover enums as int8_t, int16_t int32_t, int64_t, uint8_t, uint16_t, uint32_t, and uint64_t both for DWARF and dSYM cases. The DWARF being emitted by clang is missing the enum integer type, but the code is now ready to accept and deal with the integral type if it is supplied.

This patch is designed for minimal intrusion into normal preprocessing

generate tok::comment nodes since it is preserving all whitespace, but
the output printer will then throw it away.

Jordan Rose 864b810739 Preprocessor: don't consider // to be a line comment in -E -std=c89 mode.
It's beneficial when compiling to treat // as the start of a line
comment even in -std=c89 mode, since it's not valid C code (with a few
rare exceptions) and is usually intended as such. We emit a pedantic
warning and then continue on as if line comments were enabled.
This has been our behavior for quite some time.

However, people use the preprocessor for things besides C source files.
In today's prompting example, the input contains (unquoted) URLs, which
contain // but should still be preserved.

This change instructs the lexer to treat // as a plain token if Clang is
in C90 mode and generating preprocessed output rather than actually compiling.

Meador Inge b904e6e467 Add more functions to the TLI.
This patch adds many more functions to the target library information.
All of the functions being added were discovered while doing the migration
of the simplify-libcalls attribute annotation functionality to the
functionattrs pass.  As a part of that work the attribute annotation logic
will query TLI to determine if a function should be annotated or not.
