[PATCH] Fix Ada regressions caused by my last builtins.c patch (PR ada/23593)

[Jakub Jelinek]

Hi!

I misread what component_ref_for_mem_expr is doing.  It
doesn't skip nops etc. in between COMPONENT_REFs, only around
the first COMPONENT_REF and inside of the last COMPONENT_REF.
Bootstrapped/regtested on i386-linux, fixes the 5 Ada regressions
mentioned in the PR.
Ok for HEAD/4.0?
