c/105151 - move early walloca pass
When the walloca pass gained support for ranger the early pass
was not moved to a place where SSA form is available but remained
in the lowering pipeline. For the testcase in this bug this is
a problem because for errorneous input we still run the lowering
pipeline but here have broken SSA form which ranger does not like.
The solution is to rectify the mistake with using ranger without
SSA form and move the pass which solves both issues.

* passes.def (pass_walloca): Move early instance into
pass_build_ssa_passes to make SSA form available.
* gcc.dg/gimplefe-error-14.c: New testcase.
