If the SSA def produced by this instruction is only in the block in
which it is defined and is not used by ifs or phis, then we don't have
a reason to convert it to a register in
nir_lower_ssa_defs_to_regs_block().
The special case for derefs is covered by the general case, so can be
removed: at this point all derefs in the block are
materialized (i.e. the whole deref chain is in the block) and derefs
are not used in phis.
v2: Fix wrong check for if_uses. If there's such an use, the def is
not "local_to_block". (Jason)
