libopcodes: many warnings about scalar initializers

[cooljeanius]

For example:

fr30-desc.c:131:3: warning: braces around scalar initializer
  131 |   { "r0", 0, {0, {{{0, 0}}}}, 0, 0 },
      |   ^
fr30-desc.c:131:3: note: (near initialization for 'fr30_cgen_opval_gr_names_entries[0].attrs.nonbool[0]')
fr30-desc.c:131:3: warning: braces around scalar initializer
fr30-desc.c:131:3: note: (near initialization for 'fr30_cgen_opval_gr_names_entries[0].attrs.nonbool[0]')
fr30-desc.c:131:24: warning: excess elements in scalar initializer
  131 |   { "r0", 0, {0, {{{0, 0}}}}, 0, 0 },
      |                        ^

I have a gcc bug open to make this warning disableable: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103210
...but even if that's fixed, I should still fix the underlying issue... will probably require learning how cgen and scheme work...

will probably require learning how cgen and scheme work...

Adding the "help wanted" tag for this part...

Update: split that part out into issue #69
