2214dc0764 Fix pr5470. Tablegen handles template arguments by temporarily setting their 
values, resolving references to them, and then removing the definitions.
If a template argument is set to an undefined value, we need to resolve
references to that argument to an explicit undefined value.  The current code
leaves the reference to the template argument as it is, which causes an
assertion failure later when the definition of the template argument is
removed.

a58a04921d Make Loop::getLoopLatch() work on loops which don't have preheaders, as 
it may be used in contexts where preheader insertion may have failed due
to an indirectbr.

Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in
the case that it would require splitting an indirectbr edge.

These fix PR5502.

c088ae8b84 Fix PR5558, which was caused by a wrong fix for PR3393 (see commit 63048), 
which was an expensive checks failure due to a bug in the checking.  This
patch in essence reverts the original fix for PR3393, and refixes it by a
tweak to the way expensive checking is done.

not alias with a value resulting from a load.

dab249b3b7 Enable hoisting of loads from constant memory by default. In cases where 
they are lowered to instruction sequences more complex than a simple
load, such that CodeGen cannot rematerialize them, a reload from a
spill slot is likely to be cheaper than the complex sequence.
