[PATCH] Fix PR tree-optimization/44885

[Eric Botcazou]

Hi,

this is the failure of gnat.dg/aliasing3.adb on 32-bit platforms exposed by 
the mem-ref2 merge.  But the root cause is a latent problem in IPA-SRA: the 
pass takes the address of a component of a TYPE_NONALIASED_COMPONENT array.

Proposed fix attached, tested on x86-64-suse-linux, OK for mainline?

	PR tree-optimization/44885
	* tree-sra.c (find_param_candidates): Skip pointer types to arrays
	with non-aliased component.
