Move the handling for catching asserts when we start decoding garbage
into disasm-a3xx. This way it can also cover other cases where cffdec
tries to disassemble memory, such as SP_xS_OBJ_START.

The fixes tag isn't so much because it was incorrect before, but because
I'm going to send a kernel patch to fix the typo, and that will break
old crashdec.

This is mainly for the benefit of automated syncing of changes from mesa
back to envytools, where the same subdir meson.build's are used, but the
toplevel meson.build is different. In the envytools case, we want these
depenendencies to be required.

The decode tools aren't too useful to install without the xml. But
since libxml2 can read compressed xml, we'll gzip them for installation.

Merge the extra tracking that is useful for generating stats from asm
(as opposed to ir), and for guestimating things like inputs and outputs
(mostly useful for r/e) into ir3's version and drop cffdec's version.
There is a small change in disasm output for the decode tools, in that
it no longer prints the used consts, but rather just the max accessed
const. This is the more useful piece of information, and avoids making
the shared regmask type big enough to deal with the const reg file.
Additional error checking for invalid regids causes crashdec to bail
out sooner when decoding memory that *might* hold valid instructions.
Also, crashdec no longer prints stats, because stats aren't very useful
when trying to decode random instruction memory (which might or might
not be valid instructions).

When this code was outside of the mesa tree, we needed our own enum.
Now we can use a common one, to simplify deduplicating the disasm
code.

cffdump, crashdec, etc
At this point there is some duplication with other files in-tree (ie.
a2xx and a3xx+ disassembly), which will be cleaned up in a later commit.
