Fix HP-PA C++ failures

Fix HP-PA C++ failures

[Jan Hubicka]

Hi,
On HPPA the collect2 is collecting also static symbols leading to link
errors since my changes to constructors/destructors mechanizm.
This patch avoids it by making those ctors/dtors always inline as was
originally suggested by Mark anyway.

Bootstrapped/regtested i686-linux and hppa. Comitted.
I apologize for the delays with comitting the patch, I lost track here.

	* cgraphunit.c (record_cdtor_fn): Declare all cdtors always inlined.
	(cgraph_process_new_functions): Honor previous value of
	disregard_inline_limits.
	* ipa-inline.c (compute_inline_parameters): Likewise.
