Subject: [PATCH 05/27] perf tools: Handle completion of upper case events

From: Andi Kleen <ak@...ux.intel.com>

Vendor events are often specified in upper case. perf list outputs them
in lower case. Handle this case in perf-completion.sh so that completion
on the upper case events still works.

v2: Use locale aware check for upper case
v3: Use perf list json
