PNaCl: Add ReplacePtrsWithInts pass for stripping out pointer types
ReplacePtrsWithInts converts IR to a normal form in which functions
don't reference any aggregate pointer types and pointer types only
appear inside a few instructions.
Change BlockAddress::replaceUsesOfWithOnConstant() to handle changing
a function's type by replacing a function with a bitcast ConstantExpr
of a new function.
BUG=https://code.google.com/p/nativeclient/issues/detail?id=3343
TEST=replace-ptrs-with-ints.ll + PNaCl toolchain trybots, torture tests, etc.
