Introduces BranchProbability. Changes unsigned to uint32_t all over and
uint64_t only when overflow is expected.

This is important for the correct lowering of unwind instructions
(which doesn't matter at all) and llvm.eh.resume calls (which does).

Third pass at allowing plugins to modify default passes.  This time with a tweak so that we don't depend on an uninitialized argument.

Second pass at allowing plugins to modify default passes.  This time without bonus inter-library dependencies.

Let Objective-C front-end identify class extension, in dwarf output, using an attribute DW_AT_APPLE_objc_class_extension.

This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

comments claimed it did this, but the LHS value was actually an unused variable.

The new system considers only the '-foo' part when comparing it for typos
against flags that have values, but still look at the whole string for flags
that don't. That way, we'll still correct '-inst=combine' to '-instcombine'.

Windows/DynamicLibrary.inc: Clean up ELM_Callback. We may check the decl instead of the versions of individual libraries.

autoconf: Add checking ELM_Callback decl for mingw32 and mingw-w64.
cmake/config-ix.cmake: Add checking ELM_Callback decl for win32.

Add MemoryBuffer::getBufferKind() to report whether a memory buffer uses malloc'ed or mmap'ed memory.  This is for performance analysis.

Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing.

     used by Clang.  To help Clang integration, the PTX target has been split
     into two targets: ptx32 and ptx64, depending on the desired pointer size.

- Add GCCBuiltin class to all intrinsics
