[PATCH 1/5] perf parse-events: Set numeric term config

From: John Garry
Date: Thu Sep 16 2021 - 08:39:40 EST


For numeric terms, the config field may be NULL as it is not set from the
l+y parsing.

Fix by setting the term config from the term type name.

Also fix up the pmu-events test to set the alias strings to set the period
term properly, and fix up parse-events test to check the term config
string.
