[rfc] [01/14] Const-correctness fix - irix5nat.c

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

Hello,

this patch changes irix5-nat.c fill_ routines to use 
regcache_raw_collect instead of regcache_raw_read and
related routines.

Bye,
Ulrich


ChangeLog:

	* irix5-nat.c (fill_gregset): Use regcache_raw_collect instead
	of regcache_raw_read_signed.
	(fill_fpregset): Use regcache_raw_collect instead of
	regcache_raw_read.
