[pushed] analyzer: cleanups [PR112655]

[David Malcolm]

Avoid copying eedges in infinite_loop::infinite_loop.

Use initializer lists in the various places reported in
PR analyzer/112655 (apart from coord_test's ctor, which
would require nontrivial refactoring).

Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.
Pushed to trunk as r14-6549-g8cf5afba5dc482

gcc/analyzer/ChangeLog:
	PR analyzer/112655
	* infinite-loop.cc (infinite_loop::infinite_loop): Pass eedges
	via rvalue reference rather than by value.
	(starts_infinite_loop_p): Move eedges when constructing an
	infinite_loop instance.
	* sm-file.cc (fileptr_state_machine::fileptr_state_machine): Use
	initializer list for states.
	* sm-sensitive.cc
	(sensitive_state_machine::sensitive_state_machine): Likewise.
	* sm-signal.cc (signal_state_machine::signal_state_machine):
	Likewise.
	* sm-taint.cc (taint_state_machine::taint_state_machine):
	Likewise.
	* varargs.cc (va_list_state_machine::va_list_state_machine): Likewise.
