rs6000_output_move_128bit and drop the use of the string

Subject: PR 71020: Handle abnormal PHIs in tree-call-cdce.c
From: Richard Sandiford <richard.sandiford@arm.com>
Gcc: private.sent
--text follows this line--
The PR is about a case where tree-call-cdce.c causes two abnormal
PHIs for the same variable to be live at the same time, leading to
a coalescing failure. It seemed like getting rid of these kinds of
input would be generally useful, so I added a utility to tree-dfa.c.
Tested on x86_64-linux-gnu.

libgccjit performs numerous checks at the API boundary, but
if these succeed, it ignores errors and other diagnostics emitted
within the core of gcc, and treats the compile of a gcc_jit_context
as having succeeded.
This patch ensures that if any diagnostics are emitted, they
are visible from the libgccjit API, and that the the context is
flagged as having failed.
For now any kind of diagnostic is treated as a jit error,
so warnings and notes also count as errors.

* dummy-frontend.c: Include diagnostic.h.
(jit_begin_diagnostic): New function.
(jit_end_diagnostic): New function.
(jit_langhook_init): Register jit_begin_diagnostic
