Subject: [PATCH 4.20 066/145] perf tools: Use fallback for sample_addr_correlates_sym() cases

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adrian Hunter <adrian.hunter@...el.com>

commit 225f99e0c811e23836c4911a2ff147e167dd1fe8 upstream.

thread__resolve() is used in the sample_addr_correlates_sym() cases
where 'addr' is a destination of a branch which does not necessarily
have the same cpumode as the 'ip'. Use the fallback function in that
case.

This patch depends on patch "perf tools: Add fallback functions for
cases where cpumode is insufficient".
