Also, turn on Objective-C/C++ tests.
This should fix http://llvm.org/bugs/show_bug.cgi?id=3499.

Fix PR3486. Fix a bug in code that manually patch physical register live interval after its sub-register is coalesced with a virtual register.

If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

Right now if the coalesced copy def is dead and its src is a kill, and that
there are now other uses within the live range, the coalescer would mark the
def of the source register as dead. But it should also check if there are
other kills which means the value has other uses not in the live range.

the "system dirs win over user dirs" logic to framework and headermap
search locations as well as normal directories.  This means that
clang t.m -F/System/Library/Frameworks  will treat /System/Library/Frameworks
as a system directory not a user directory.  If you use -v, the difference is:

Before:
ignoring nonexistent directory "/usr/libdata/gcc41"
ignoring duplicate framework "/System/Library/Frameworks"
#include "..." search starts here:
#include <...> search starts here:

After:
ignoring nonexistent directory "/usr/libdata/gcc41"
ignoring duplicate directory "/System/Library/Frameworks"
  as it is a non-system directory that duplicates a system directory
#include "..." search starts here:
#include <...> search starts here:
