[InstCombine] Handle PHI nodes in PtrReplacer
This patch adds on to the functionality implemented
in rG42ab5dc5a5dd6c79476104bdc921afa2a18559cf,
where PHI nodes are supported in the use-def traversal
algorithm to determine if an alloca ever overwritten
in addition to a memmove/memcpy. This patch implements
the support needed by the PointerReplacer to collect
all (indirect) users of the alloca in cases where a PHI
is involved. Finally, a new PHI is defined in the replace
method which takes in replaced incoming values and
updates the WorkMap accordingly.
