the operands have pointer type, so that the resulting type matches
the original SCEV type, and so that unnecessary ptrtoints are
avoided in common cases.

MOV32r0 + subregs to do the same thing.  This should work now
that PR4544 is fixed.  Thanks Evan!

Have asm printers use formatted_raw_ostream directly to avoid a
dynamic_cast<>.

For now this only computes the allocated size of the memory pointed to by a
pointer, and offset a pointer from allocated pointer.
The actual checkLimits part will come later, after another round of review.

additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

This results in the pass manager running IVUsers only once for
indvars, instead of twice.

Fix by making the LLVM_UNREACHABLE pass __FILE__ and __LINE__ to
llvm_unreachable.
