Shaw Young 131eb30584 [BOLT] Match blocks with calls as anchors (#96596) ...

Added another hash level – call hash – following opcode hash matching
for stale block matching. Call hash strings are the concatenation of the
lexicographically ordered names of each blocks’ called functions. This 
change bolsters block matching in cases where some instructions have
been removed or added but calls remain constant.

Test Plan: added match-functions-with-calls-as-anchors.test.
