[llvm-commits] [PATCH] ConstantFolding.cpp: Make Big-endian aware

[NAKAMURA Takumi]

Make ReadDataFromGlobal() and FoldReinterpretLoadFromConstPtr() were not performed when target is big endian.

It caused failure in Clang :: CodeGen___bitfield-promote.c on ppc.

Some tests are made to check with both endian.
