ssijaric-nv 6789442eb2 [AArch64] Fix a corner case with large stack allocation (#122038) ...

In the unlikely case where the stack size is greater than 4GB, we may run into
the situation where the local stack size and the callee saved registers stack
size get combined incorrectly when restoring the callee saved registers. This
happens because the stack size in shouldCombineCSRLocalStackBumpInEpilogue
is represented as an 'unsigned', but is passed in as an 'int64_t'. We end up with
something like

$fp, $lr = frame-destroy LDPXi $sp, 536870912

This change just makes 'shouldCombineCSRLocalStackBumpInEpilogue' match
'shouldCombineCSRLocalStackBump' where 'StackBumpBytes' is an 'uint64_t'
