b5fe25544c Split SelectionDAGISel::IsLegalAndProfitableToFold to
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

adc600ceb5 When testing whether a given SCEV depends on a temporary symbolic
name, test whether the SCEV itself is that temporary symbolic name,
in addition to checking whether the symbolic name appears as a
possibly-indirect operand.

de32b2fac0 When complicated expressions are broken down into subexpressions
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.

Otherwise AT&T asm printer is used with non-compatible MCAsmInfo and
there is no way to override this behaviour.

dbffcb6c92 Actually, this code doesn't have to be quite so conservative in
the no-TLI case. But it should still default to declining the
transformation.

4d5f3b74e4 In rememberInstruction, if the value being remembered is the
current insertion point, advance the current insertion point.
This avoids a use-before-def situation in a testcase extracted
from clang which is difficult to reduce to a reasonable-sized
regression test.
