[Fortran, Patch, pr70524, v1] [5/6/7 Regression] ICE when using -frepack-arrays -Warray-temporaries

[Andre Vehreschild]

Hi all,

the attached patch fixes the ICE when the options in the title are
used. Two issues caused this ICE:

1. the error-printing routines relied on the locus.nextc which was not
set by the gfc_set_backend_locus() and is now set by the patch
(locally, not in gfc_set_backend_locus()).

2. the locus of the function whose result triggered the warning (and
with it the ICE) was set too late.

Both issues are addressed by the patch. Albeit I am not quite sure,
whether my solution to 1. (the first chunk in the patch) is ok this
way.

Bootstraps and regtests ok on x86_64-linux-gnu/F23.

Ok for trunk? And with one week delay for gcc-5- and -6-branch?

Regards,
	Andre
