Keith Randall 5428570af7 cmd/compile: use call block instead of entry block for tail call expansion
The expand-calls pass assumed that tail calls were always done in the
entry block. That used to be true, but with tail calls in wrappers
(enabled by CL 578235) and libfuzzer instrumentation, that is no
longer the case. Libfuzzer instrumentation adds an IF statement to the
start of the wrapper function.

Fixes #69825
