Fix a bug in the local spiller, where we could take code like this:
...
store r12 -> [ss#2]
R3 = load [ss#1]
use R3
R3 = load [ss#2]
R4 = load [ss#1]
and turn it into this code:
store R12 -> [ss#2]
R3 = load [ss#1]
use R3
R3 = R12
R4 = R3 <- oops!
The problem was that promoting R3 = load[ss#2] to a copy missed the fact that
the instruction invalidated R3 at that point.

Fix some faulty logic in the libcall inserter.
...
Since calls return more than one value, don't bail if one of their uses
happens to be a node that's not an MVT::Other when following the chain
from CALLSEQ_START to CALLSEQ_END.
Once we've found a CALLSEQ_START, we can just return; there's no need to
tail-recurse further up the graph.
Most importantly, just because something only has one use doesn't mean we
should use it's one use to follow from start to end. This faulty logic
caused us to follow a chain of one-use FP operations back to a much earlier
call, putting a cycle in the graph from a later start to an earlier end.
This is a better fix that reverting to the workaround committed earlier
today.

into:

Unfortunately, this is actually worse code, because the register coallescer
is getting confused somehow. If it were doing its job right, it could turn the
code into this:
_test:
cmpwi cr0, r4, 0
bgt cr0, LBB_test_2 ; entry.no_exit_crit_edge
LBB_test_1: ; entry.loopexit_crit_edge

This break is bogus and I have no idea why it was there. Basically it prevents
...
memoizing code when IV's are used by phinodes outside of loops. In a simple
example, we were getting this code before (note that r6 and r7 are isomorphic
IV's):
li r6, 0
or r7, r6, r6
LBB_test_3: ; no_exit
lwz r2, 0(r3)
cmpw cr0, r2, r5
or r2, r7, r7
beq cr0, LBB_test_5 ; loopexit
LBB_test_4: ; endif
addi r2, r7, 1
addi r7, r7, 1
addi r3, r3, 4
addi r6, r6, 1
cmpw cr0, r6, r4
blt cr0, LBB_test_3 ; no_exit
Now we get:
li r6, 0
LBB_test_3: ; no_exit
or r2, r6, r6
lwz r6, 0(r3)
cmpw cr0, r6, r5
beq cr0, LBB_test_6 ; loopexit
LBB_test_4: ; endif
addi r3, r3, 4
addi r6, r2, 1
cmpw cr0, r6, r4
blt cr0, LBB_test_3 ; no_exit
this was noticed in em3d.

Minor tweak to the branch selector. When emitting a two-way branch, and if
...
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch. For example, emit this:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
ble cr0, LBBl29_z__44
b LBBl29_z__48 *** NOT PART OF LOOP
Instead of:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
bgt cr0, LBBl29_z__48 *** PART OF LOOP!
b LBBl29_z__44
The former sequence has one fewer dispatch group for the loop body.
