a8b6f68a55 This is a carefully contrived testcase where the X86 ISel is emitting all loads
before other ops, causing it to spill like mad.  This occurs in
164.gzip:flush_block.

61b8c9bf94 The pattern isel is aggressively codegen'ing all of the loads in these
functions together at the start of the basic block, causing massive spillage.
The old isel codegened the loads wherever they happened to land, so it
generated good code for the first case, but bad code for the second.

We really want the pattern isel to generate (the same) good code for both.
