Return early from getUnconditionalBranchTargetOpValue if the branch target is

When getUnconditionalBranchTargetOpValue is called with an MCExpr target, we
don't know what the final immediate field value should be. We shouldn't
explicitly set the immediate field to an encoded zero value as zero is encoded
with a non-zero bit pattern. This leads to bits being set that pollute the

the TBAA information can legitimately be carried over.

The patch adds alternative forms of getLoad() and getExtLoad() that take
a MachineMemOperand instead of individual fields.  (The corresponding
getTruncStore() already exists.)  The idea is to use the MachineMemOperand
forms when all fields are carried over (size, pointer info, isVolatile,
isNonTemporal, alignment and TBAA info).  If some adjustment is being
made, e.g. to narrow the load, then we still pass the individual fields

increases the default limit to a level at which these tests pass.
