This patch is to fix lit test case failure relate to alignment, on z/OS, maximum alignment value for 64 bit mode is 16 and also fixed clang/test/Layout/itanium-union-bitfield.cpp, attribute ((aligned(4))) is needed for bit-field member in Union for z/OS because single bit-field has one byte alignment, this will make sure size and alignment will be correct value on z/OS.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
