Reformat PseudoSourceValue.cpp and PseudoSourceValue.h. NFC.
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@244685 91177308-0d34-0410-b5e6-96231b3b80d8
