The GCC internal %G directive takes a gcall* argument and prints
the call's inlining stack in diagnostics. The argument type makes
it unsuitable for gimple expressions such as those diagnosed by

As the first step in adding inlining context to -Warray-bounds
warnings the attached
Attached is a much scaled-down patch that only adds a note
to the -Warray-bounds warnings mentioning the declaration
to which the out-of-bounds index or offset applies.
Printing the inlining context needs a bit more work but
this small improvement can be made independently of it.

This is an old patch which removes the struct map from the nvptx plugin.
I believe at one point this was supposed to be used to manage async data
mappings, but in practice that never worked out.
Is this OK for trunk? I bootstrapped and regtested on x86_64 with nvptx
