A quick experiment reveals that this hack is needed for C code - simply
removing this hack entirely breaks the build of libstdc++, since
regs.h (more accurately, the cpu-specific header it pulls in) defines
structs in terms of types from vxTypesOld. Those definitions are
properly guarded by #ifndef _ASMLANGUAGE, but the cpu-files do not take
care to include vxTypesOld.h for the types they depend on.

But when using regs.h from some assembly file, the assembler chokes on
the typedefs in vxTypesOld.h. We can fix that by guarding the include of
vxTypesOld by !_ASMLANGUAGE. This should not affect existing C code.

Now, the OS' regs.h contains preprocessor conditionals such as

#if     CPU_FAMILY==I960
...
#endif  /* CPU_FAMILY==I960 */
#if     CPU_FAMILY==MC680X0
...
#endif  /* CPU_FAMILY==MC680X0 */

Without definitions of CPU_FAMILY, I960 etc., these would all be true,
which will not end well. Code using the fix-included regs.h
automatically get vxCpu.h via a chain of includes from vxTypesOld.h, but
we can make regs.h a little more self-contained for both C and asm users
by doing an explicit include of vxCpu.h.

This patch adds a minimum width to the left margin used for printing
line numbers.   I set the default to 6.  Hence rather than:

some-filename:9:1: some message
9 | some source text
  | ^~~~~~~~~~~~~~~~
some-filename:10:1: another message
10 | more source text
   | ^~~~~~~~~~~~~~~~

we now print:

some-filename:9:42: some message
    9 | some source text
      | ^~~~~~~~~~~~~~~~
some-filename:10:42: another message
   10 | more source text
      | ^~~~~~~~~~~~~~~~

This implicitly fixes issues with margins failing to line up due
to different lengths of the number when we haven't read the full
file yet and so don't know the highest possible line number, for
line numbers up to 99999.

Doing so adds some whitespace on the left-hand side, for non-huge
files, at least.  I believe that this makes it easier to see where each
diagnostic starts, by visually breaking things up at the leftmost
column; my hope is to make it easier for the eye to see the different
diagnostics as if they were different "paragraphs".

The warnings about changes to empty struct parameter passing can be
ignored because the callers are all internal to the library, and so
compiled with the same -fabi-version as the function definitions.

It would be preferable to use #pragma GCC diagnostic warning "-Wabi=12"
to get warnings about any other ABI changes in future versions, but
until PR c++/87611 is fixed the warnings must be completely disabled
