tree-optimization/103188 - avoid running ranger on not-up-to-date SSA
The following splits loop header copying into an analysis phase
that uses ranger and a transform phase that can do without to avoid
running ranger on IL that has SSA form not updated.

* tree-ssa-loop-ch.c (should_duplicate_loop_header_p):
Remove query parameter, split out check for size
optimization.
(ch_base::m_ranger, cb_base::m_query): Remove.
(ch_base::copy_headers): Split processing loop into
analysis around which we allocate and use ranger and
transform where we do not.
(pass_ch::execute): Do not allocate/free ranger here.
(pass_ch_vect::execute): Likewise.
* gcc.dg/torture/pr103188.c: New testcase.
