Remove unnecessary temporary in tree-if-conv.c
The call to ifc_temp_var in predicate_mem_writes become redundant
in r230099. Before that point the mask was calculated using
fold_build_*s, but now it's calculated by gimple_build and so
is already a valid gimple value.
As it stands, the call forces an SSA_NAME-to-SSA_NAME copy
to be created, whereas SLP expects that such redundant copies
have already been eliminated.
