[patch] Ad PR81487: More asprintf -> xasprintf replacements

[Georg-Johann Lay <avr at gjlay dot de>]

Hi, as proposed in

https://gcc.gnu.org/ml/gcc-patches/2017-07/msg01294.html

this patch does more asprintf -> xasprintf replacements.

Bootstrapped + reg-tested on x86_64-linux.

Ok for trunk?

Johann

	PR 81487
	* hsa-brig.c (brig_init): Use xasprintf instead of asprintf.
	* gimple-pretty-print.c (dump_profile, dump_probability): Same.
	* tree-ssa-structalias.c (alias_get_name): Same.
