[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.
