nir: Produce intrinsics in lower_{phis,ssa_defs}_to_regs
...
A number of passes lower SSA partially to registers, do work that would be
invalid in SSA, and then go back into SSA with nir_lower_regs_to_ssa. As a step
towards replacing nir_register with intrinsics,
the nir_lower_{phis,ssa_defs}_to_regs passes are changed to produce intrinsics
instead of nir_registers, and their callers are updated to call
nir_lower_reg_intrinsics_to_ssa instead of nir_lower_regs_to_ssa to compensate.

nir: Convert to nir_foreach_function_impl
...
Done by hand at each call site but going very quickly with funny Vim motions and
common regexes. This is a very common idiom in NIR.

nir/lower_continue_constructs: special-case Continue Constructs with zero or one predecessors
...
If a loop has only a single continue, the control flow is already
converged and we can inline the continue construct.
If a loop has no continue statement at all, the Continue Construct
is unreachable and can simply be deleted.

by inserting it at the beginning of the loop:
loop {
if (i != 0) {
continue construct
}
loop body
