  [SampleProfile] Fix FuncMappings key mismatch for renamed functions in stale profile matching (#187899)

Fix a bug where `distributeIRToProfileLocationMap` fails to find
location mappings from IR to profile for renamed functions because
`FuncMappings` is indexed by the IR function name while
`distributeIRToProfileLocationMap` looks up by the profile function
name. Fixed by making `FuncMappings` to use profile function name as
key.
