[committed/Darwin]: fix fetch of amd64 fpu registers

[Tristan Gingold]

Hi,

this patch fixes a typo in i386-darwin-nat.c so that fpu registers are  
correctly supplied in amd64 case.

Tristan.

	* i386-darwin-nat.c (i386_darwin_fetch_inferior_registers): Use
	amd64_supply_fxsave for amd64.  Fix the offset.
	(i386_darwin_store_inferior_registers): Use amd64_collect_fxsave
	for amd64.
