*	Don't spill PPC VRSAVE on non-Darwin (even in SjLj)	Hal Finkel	2013-03-27
\| \| \| \| \| \| \| \| \| \| \| \| \|	As Bill Schmidt pointed out to me, only on Darwin do we need to spill/restore VRSAVE in the SjLj code. For non-Darwin, don't spill/restore VRSAVE (and I've added some asserts to make sure that we're not). As it turns out, we're not currently handling the Darwin case correctly (I've added a FIXME in the test case). I've tried adding various implied register definitions/uses to force the spill without success, so I'll need to address this later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178096 91177308-0d34-0410-b5e6-96231b3b80d8
*	Add support for spilling VRSAVE on PPC	Hal Finkel	2013-03-21
	Although there is only one Altivec VRSAVE register, it is a member of a register class, and we need the ability to spill it. Because this register is normally callee-preserved and handled by special code this has never before been necessary. However, this capability will be required by a forthcoming commit adding SjLj support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177654 91177308-0d34-0410-b5e6-96231b3b80d8
