The code building the code completion string for overloads was providing
less detail compared to the one building completion strings for function
declarations. There was no information about optionals and no information
about what's a parameter and what's a function identifier, everything
besides ResultType, CurrentParameter and special characters was classified
as Text.
This makes code completion strings for overload candidates to follow a
pattern very similar, but not identical, to the one in use for function
declarations:
- return type chunk: ResultType
- function identifier chunk: Text
- parameter chunks: Placeholder
- optional parameter chunks: Optional
- current parameter chunk: CurrentParameter

Introduce SPIR calling conventions.
This implements Section 3.7 from the SPIR 1.2 spec:
SPIR kernels should use "spir_kernel" calling convention.
Non-kernel functions use "spir_func" calling convention. All
other calling conventions are disallowed.
The patch works only for OpenCL source. Any other uses will need
to ensure that kernels are assigned the spir_kernel calling
convention correctly.

This moves classes for storing and applying replacements to separate

dropped. This causes issues for tools that use the serialized

driver diagnostics into a single file when the driver invokes CC1.

We currently use a null FailingCommand when generating crash reports
as an indication that the cause is FORCE_CLANG_DIAGNOSTICS_CRASH, the
environment variable that exists to test crash dumps. This means that
our tests don't actually cover real crashes at all, and adds a more
complicated code path that's only used in the tests.
Instead, we can have the driver synthesize that every command failed

that we were doing this wrong. I've also updated the error check to

This bug happens because the /link (clang-cl.exe argument) is marked as

MemoryBuffers are immutable and the general convention in the LLVM

Due to what can only be described as a CRT bug, stdout and amazingly
even stderr are not always flushed upon process termination, especially
when the system is under high threading pressure. I have found two
repros for this:
1) In lib\Support\Threading.cpp, change sys::Mutex to an
std::recursive_mutex and run check-clang. Usually between 30 and 40
tests will fail.
2) Add OutputDebugStrings in code that runs during static initialization
and static shutdown. This will sometimes generate similar failures.
After a substantial amount of troubleshooting and debugging, I found
that I could reproduce this from the command line without running
check-clang. Simply make the mutex change described in #1, then
manually run the following command many times by running it once, then
pressing Up -> Enter very quickly:
D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1 -Xclang -error-on-deserialized-decl=TopVar | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1
Sporadically they will fail, and attaching a debugger to a failed
instance indicates that stdin of FileCheck.exe is empty.
Note that due to the repro in #2, we can rule out a bug in the STL's
mutex implementation, and instead conclude that this is a real flake in
the windows test harness.

Code completion diagnostics referred to data stored in CXCodeCompleteResults
