b7c81e9952 Switch to ANSI C style C function declarations.
main(argc, argv) --> int main(int argc, char** argv)

Although we accept int, void, and char types, and pointers to same,
we actually still treat everything as an int.

ac0e95eb60 Improve ACC error reporting.
Now return an error code and an error message, rather than just
printing to stderr or calling exit().

Check to see we don't exceed our code size.

a653561097 ARM codegen: Add disassembler, implement return
This program works:

    main() { return 42; }

The disassembler was borrowed from codeflinger, and just modified enough to compile
under C++ without warnings.

Implemented gsym
Implemented a hack verison of li, only works for -256..255
Implemented gjmp

e27bf3eb29 Replace acc.c with the contents of otccn.c, update tests.
We are no longer checking if the constant data is the same, just the
generated code.
