[PATCH] D60856: [CodeGen] Add "const" to MachineInstr::mayAlias

[Bjorn Pettersson via Phabricator via llvm-commits]

Herald added a project: LLVM.

The basic idea here is to make it possible to use
MachineInstr::mayAlias also when the MachineInstr
is const (or the "Other" MachineInstr is const).

The addition of const in MachineInstr::mayAlias
then rippled down to the need for adding const
in several other places, such as
TargetTransformInfo::getMemOperandWithOffset.
