Hi!
As discussed in the PR, this is a safer variant of a fix for 4.8, where
input_location during most optimization passes is set to
DECL_SOURCE_LOCATION (current_function_decl) and various parts of the
gimplifier e.g. during force_gimple_operand* may end up setting
gimple_location to that. For 4.9, we should revert this and set
input_location to UNKNOWN_LOCATION for the optimizers.
Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk.

* gimplify.c (force_gimple_operand_1): Temporarily set input_location
to UNKNOWN_LOCATION while gimplifying expr.
* gcc.dg/pr56094.c: New test.
Based on c#15, we should probably consider this a bit of a band-aid,
right? Thus we'll install the band-aid, but keep the PR open pending a
better solution for handling of input_location, correct?
