2a6b59a693 Add 'llvm_unreachable' to passify GCC's understanding of the constraints 
of several newly un-defaulted switches. This also helps optimizers
(including LLVM's) recognize that every case is covered, and we should
assume as much.

4f82b3a13f use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJIT 
Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

ba84a9652a Conform to the style guide; remove 'else' after 'return'. Also remove an extra 
if-statement by turning it into an assert. No functionality change.

77f9c9f719 Switch StringMap from an array of structures to a structure of arrays. 
- -25% memory usage of the main table on x86_64 (was wasted in struct padding).
- no significant performance change.

2147506d8b Changes the JSON parser to use the SourceMgr. 
Diagnostics are now emitted via the SourceMgr and we use MemoryBuffer
for buffer management. Switched the code to make use of the trailing
'0' that MemoryBuffer guarantees where it makes sense.

memory fences) in statistics registration, which works the same way that
ManagedStatic registration does.

b92661d00a [Win32] Catch exceptions (eg. segfault) on waiting for invoked clang from the driver. 
clang/lib/Driver/Driver.cpp: Don't pass through negative exit status, or parent would be confused.

llvm::sys::Program::Wait(): Suppose 0x8000XXXX and 0xC000XXXX as abnormal exit code and pass it as negative value.

Win32 Exception Handler: Exit with ExceptionCode on an unhandle exception.

9751c17d0d rename ENABLE_THREADS to LLVM_ENABLE_THREADS 
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

448be745f6 Fix APFloat::convert so that it handles narrowing conversions correctly; it 
was returning incorrect values in rare cases, and incorrectly marking
exact conversions as inexact in some more common cases. Fixes PR11406, and a
missed optimization in test/CodeGen/X86/fp-stack-O0.ll.

de9c504d6b Turn error recovery into an assert. 
This was put in because in a certain version of DragonFlyBSD stat(2) lied about the
size of some files. This was fixed a long time ago so we can remove the workaround.

53185e9016 Add support for tsan annotations (thread sanitizer, a valgrind-based tool). 
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!
