Rong Xu 52aa224aff [llvm-profdata] add value-cutoff functionality in show command 
This patch improves llvm-profdata show command:
(1) add -value-cutoff=<N> option: Show only those functions whose max count
    values are greater or equal to N.
(2) add -list-below-cutoff option: Only output names of functions whose max
    count value are below the cutoff.
(3) formats value-profile counts and prints out percentage.

Rong Xu 6f366c3a04 [PGO] Use SourceFileName rather module name in PGOFuncName 
In LTO or Thin-lto mode (though linker plugin), the module
names are of temp file names which are different for
different compilations. Using SourceFileName avoids the issue.
This should not change any functionality for current PGO as
all the current callers of getPGOFuncName() is before LTO.
