New Revision: 239887
URL: http://llvm.org/viewvc/llvm-project?rev=239887&view=rev
Log:
[PM/AA] Suffix lots of member variables that directly use enumeration
names for counts with the word 'Count' to make them less ambiguous.
This will be an actual error if we use unscoped enums for any of these,
and generally this seems much clearer to read.
Also, use clang-format to normalize the formatting of this code which
seems to have been needlessly odd.
No functionality changed here.
