New Revision: 140144

URL: http://llvm.org/viewvc/llvm-project?rev=140144&view=rev
Log:
Clarify PNaCl target characteristics: set LongDoubleWidth, PtrDiffType, IntPtrType,
change __builtin_va_list to from a structure to int[4] (same alignment
and size, but with a simpler representation). Patch by David Meyer!
