"This maps the -pthread option to -lpthread - this isn't 100% correct,
...
since handling this correctly is quite complex, and on some platforms
requires additional -D options and on some implies linking against a
different libc, but this works better than just ignoring the option.
The other change passes the -x option across to clang, which allows
compiling .c files as Objective-C and so on. For some reason a lot of
configure scripts seem to be under the misguided impression that this
is a sensible thing to do."

Modified the dead stores checker to...
...
1) Check if a dead store appears as a subexpression. For such cases, we emit
a verbose diagnostic so that users aren't confused. This addresses:
<rdar://problem/5968508> checker gives misleading report for dead store in loop
2) Don't emit a dead store warning when assigning a null value to a pointer.
This is a common form of defensive programming. We may wish to make
this an option to the the checker one day.
This addresses the feature request in the following email:

Enhanced heuristic to determine the *best* register to spill. Instead of picking the register with the lowest spill weight. Consider (up to) 2 additional registers with spill weights that are close to the lowest spill weight. The one with fewest defs and uses that conflicts with the current interval (weighted by loop depth) is the spill candidate.
...
This is not always a win, but there are much more wins than loses and wins tend to be more noticeable.
