perf tools: Try to show pretty printed output for dynamic sort keys
Each tracepoint event has format string for print to improve
readability. Try to parse the output and match the field name. If it
finds one, use that for the result. If not, fallbacks to the original
output.
For example, sort on kmem:kmalloc.gfp_flags looks like below:
(Note: libtraceevent plugins are not installed on my system. They might
affect the output below)
Before:
# Overhead Command gfp_flags
# ........ ....... ..........
#
99.89% perf 32848
0.06% sleep 208
0.03% perf 32976
0.01% perf 208
After:
# Overhead Command gfp_flags
# ........ ....... ...................
#
99.89% perf GFP_NOFS|GFP_ZERO
0.06% sleep GFP_KERNEL
0.03% perf GFP_KERNEL|GFP_ZERO
0.01% perf GFP_KERNEL
