Summary:
Previously, we would generate a single name for all reference
temporaries and allow LLVM to rename them for us. Instead, number the
reference temporaries as we build them in Sema.

Summary:
A reference temporary should inherit the linkage of the variable it
initializes. Otherwise, we may hit cases where a reference temporary
wouldn't have the same value in all translation units.

Almost all linkage calculation for VarDecls occured inside of
GetLLVMLinkageVarDefinition except for static data members. Centralize
the logic so that it can be more readily reused.
No functionality change.

It turns out that linkage and visibility have rather similar logic for
both functions and non-variable globals. Split the calculation out so
that both sides may share this code.
No functionality change.

Update clang to use the InstrProfReader from LLVM to read
instrumentation based profile data. This also switches us from the
naive text format to the binary format, since that's what's
implemented in the reader.
llvm-svn: 206658
This adds a warning that triggers when profile data doesn't match for
the source that's being compiled with -fprofile-instr-use=. This fires
only once per translation unit, as warning on every mismatched
function would be quite noisy.

Emitting the PGO initialization in EmitGlobalFunctionDefinition is
inefficient, since this only has an effect once per module. We move
this to Release() with the rest of the once-per-module logic.

Summary:
MSVC always emits inline functions marked with the extern storage class
specifier. The result is something similar to the opposite of
__attribute__((gnu_inline)).
This extension is also available in C.
This fixes PR19264.
