Reformat PseudoSourceValue.cpp and PseudoSourceValue.h. NFC.

Browse Source 
This commit reformats the files lib/CodeGen/PseudoSourceValue.cpp and
include/llvm/CodeGen/PseudoSourceValue.h using clang-format. This change is
done in preparation for the changes to the pseudo source value object
management and to the PseudoSourceValue's class hierarchy.
