Adding support to sort hist entries based on the outcome of selected
computation. It's now possible to specify '+' as a first character of
'-c' option value to make such sort.
Example:
$ perf diff -c ratio -b
# Event 'cache-misses'
#
# Baseline Ratio Shared Object Symbol
# ........ .............. ................. ................................
#
19.64% 0.69 [kernel.kallsyms] [k] clear_page
0.30% 0.17 [kernel.kallsyms] [k] mm_alloc
0.04% 0.20 [kernel.kallsyms] [k] kmem_cache_alloc
$ perf diff -c +ratio -b
# Event 'cache-misses'
#
# Baseline Ratio Shared Object Symbol
# ........ .............. ................. ................................
#
19.64% 0.69 [kernel.kallsyms] [k] clear_page
0.04% 0.20 [kernel.kallsyms] [k] kmem_cache_alloc
0.30% 0.17 [kernel.kallsyms] [k] mm_alloc
