[mips] Correct size_t and ptrdiff_t for N32. Summary: Correct size_t to be unsigned int and ptrdiff_t to be signed long. The types were the correct size before this change but the exact type matters for name mangling and exception handling in C++.

[Mips] Fix MIPS ABI name in the test. The name "64" is accepted by both gcc and Clang drivers but internally LLVM/Clang use the name "n64". llvm-svn: 211999

// N64-LABEL: define i64* @_Z10alloc_longv()
[mips] Promote all integral/enumeration types to the GPR width Summary: Ensure all integral/enumeration types are appropriately annotated with signext/zeroext. In particular, i32 now has these attributes when using the N32/N64 ABI. This paves the way for accurately representing the way the N32/N64 ABI's promotes integer arguments to i64.
