*	Also attempt trivial coalescing for live intervals that end in a copy.	Jakob Stoklund Olesen	2009-12-04	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	The coalescer is supposed to clean these up, but when setting up parameters for a function call, there may be copies to physregs. If the defining instruction has been LICM'ed far away, the coalescer won't touch it. The register allocation hint does not always work - when the register allocator is backtracking, it clears the hints. This patch takes care of a few more cases that r90163 missed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90502 91177308-0d34-0410-b5e6-96231b3b80d8

	physical register, it's not necessarily defined by a copy. We have to watch out it doesn't clobber any sub-register that might be live during its live interval. If the live interval crosses a basic block, then it's not safe to check with the less conservative check (by scanning uses and defs) because it's possible a sub-register might be live out of the block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62144 91177308-0d34-0410-b5e6-96231b3b80d8
