New Revision: 64495

URL: http://llvm.org/viewvc/llvm-project?rev=64495&view=rev
Log:
Give TargetInfo a new IntPtrType to hold the intptr_t type for
a target.

Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this.

On linux/32, set intptr_t to int, instead of long.  This fixes PR3563.
