Fix ICE in inline_small_functions

[Jan Hubicka <hubicka at ucw dot cz>]

Hi,
this patch fixes ICE in inline_small_functions checking consistency of the
growth cache.  When removing speculation the cache needs to be reset because
the frequencies of edges change.

Bootstrapped/regtested x86_64-linux, comitted.

	PR ipa/64565
	* g++.dg/torture/pr64565.C: New testcase.
	* ipa-inline.c (inline_small_functions): Update callee keys after
	resolving speculation
	(inline_small_functions): Always check monotonicity of the queue.
