Looks like c2go and gcc disagree about the exact meaning of the
usual arithmetic conversions, in a way that broke 9l's archreloc.
Fix it.
It's very hard for me to see why the original C code did not say
what c2go interpreted it to say, but apparently it did not.
This is why Go has explicit numerical conversions.

This CL will break any uses of 'go tool 5a' etc.
That is intentional.
Code that invokes an assembler directly should be updated to use go tool asm.
We plan to keep the old5a around for bit-for-bit verification during
the release testing phase, but we plan to remove those tools for the
actual release. Renaming the directory now makes sure that lingering
references to 'go tool 5a' will be caught, changed to use asm, and
tested during the release evaluation.

Plan 9 provides a /dev/random device to return a
stream of random numbers. However, the method used
to generate random numbers on Plan 9 is slow and
reading from /dev/random may block.
We don't want our Go programs to be significantly
slowed down just to slightly improve the distribution
of hash values.
So, we do the same thing as NaCl and rely exclusively
on extendRandom to generate pseudo-random numbers.

Clean up the obj API by making Rconv (register pretty printer) a top-level
function. This means that Dconv (operand pretty printer) doesn't need
an Rconv argument.
To do this, we make the register numbers, which are arbitrary inside an
operand (obj.Addr), disjoint sets for each architecture. Each architecture
registers (ha) a piece of the space and then the global Rconv knows which
architecture-specific printer to use.
Clean up all the code that uses Dconv.
Now register numbers are large, so a couple of fields in Addr need to go
from int8 to int16 because they sometimes hold register numbers. Clean
up their uses, which meant regenerating the yacc grammars for the
assemblers. There are changes in this CL triggered by earlier changes
to yacc, which had not been run in this directory.
There is still cleanup to do in Addr, but we're getting closer to that being
easy to do.
