Given something like:
void *v = (void *)100;

We need to synthesize a ptrtoint operation from 100.  During constant
emission, we choose i64 as the type for our constant because it
guaranteed not to drop any bits from our CharUnits representation of the
value.  However, this is suboptimal for 32-bit targets: LLVM passes like
GlobalOpt will get confused by these sorts of casts resulting in
pessimization.

Instead, make sure the ptrtoint operand has a pointer-sized integer
type.

This mirrors the many other -i*after options to insert a new system search
directory at the end of the search path.  This makes it possible to actually
inject a search path after the resource dir.  This option is similar in spirit
to the /imsvc option in the clang-cl driver.  This is needed to properly use the
driver for Windows targets where the clang headers wrap some of the system
headers.

This concept is actually useful on other targets (e.g. Linux) and would be
really easy to support on the core toolchain.

 - In functions with try { } catch { }, only the try block would be
   skipped, not the catch blocks

 - The template functions would still be parsed.

 - The initializers within a constructor would still be parsed.

 - The inline functions within class would still be stored, only to be
   discared later.

 - Invalid code with try would assert (as in "int foo() try assert_here")

This attempt to do even less while skipping function bodies.
