Quentin Colombet	a407cc079c	[GlobalISel] Add a localizer pass for target to use ... This reverts commit r299287 plus clean-ups. The localizer pass is a helper pass that could be run at O0 in the GISel pipeline to work around the deficiency of the fast register allocator. It basically shortens the live-ranges of the constants so that the allocator does not spill all over the place. Long term fix would be to make the greedy allocator fast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@304051 91177308-0d34-0410-b5e6-96231b3b80d8	2017-05-27 01:34:00 +00:00
