Generate a C struct with the data, and use that, instead of an
assembly language file. The assembly language causes issues on
Darwin and MS-Windows, which don't necessarily use GNU AS; or
if they do, don't necessarily use its ELF syntax.
It's also better in two other ways: fewer global symbols; and
the init-time size check gets optimized away at compile time.
(Unless it fails, in which case bigger chunks of the file vanish.)

Load the XScale debug handler from the read-only data section
instead of from a separate file that can get lost or garbaged.
This eliminates installation and versioning issues, and also
speeds up reset handling a bit.
Plus some minor bits of cleanup related to loading that handler:
comments about just what this handler does, and check fault codes
while writing it into the mini-icache.
The only behavioral changes should be cleaner failure modes after
errors during handler loading, and being a bit faster.
NOTE: presumes GNU assembly syntax, with ".incbin"; and ELF,
because of the syntax of the ".size" directive.
