Preprocessed source for cselib.c

Hi!

Just ran into another ICE which occurs when compiling libjpeg-turbo on SH:

jidctflt.c: In function 'jpeg_idct_float':
jidctflt.c:237:1: internal compiler error: in cselib_record_set, at
cselib.c:2396
 }

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccHHXJkq.out file, please attach this to
your bugreport.

This definitely looks like a regression as the same upstream version 1.4.1 of
libjpeg-turbo previously built fine with gcc-4.9 [1].

Attaching the pre-processed C sources with this bug report. The full build log
can be found in [2].
