We create a distinct type for each field in a packed record with a
gnu_size, but there is no distinct debug information for them. Use
the same unpacked type for debug information.
Regstrapped on x86_64-linux-gnu. Pre-approved by Eric. I'm checking it
in.
for gcc/ada/ChangeLog
* gcc-interface/decl.cc (gnat_to_gnu_field): Use unpacked type
as the debug type for packed fields.
for gcc/testsuite/ChangeLog
* gnat.dg/bias1.adb: Count occurrences of -7.*DW_AT_GNU_bias.

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
