[Bug target/38134] [4.4 Regression] speed regression with many loop invariants

It seems to me that it would help to have a postreload LIM pass that would
concentrate on loop-invariant memory accesses that are as cheap or cheaper than
loading back a spill.  These would be excluded from the current (non-strict)
LIM.  Is it crazy?
