This function is basically just a big switch statement. Earlier versions
used tables to look up the function to use, but
- if the table contains both assembler and disassembler functions then
the disassembler contains much of the assembler and vice-versa,
- there's a lot of inlining possibilities as things grow,
- using a switch statement avoids the function call overhead.

This routine is called for each instruction to be assembled.
STR points to the insn to be assembled.
We assume all necessary tables have been initialized.
The assembled instruction, less any fixups, is stored in BUF.
Remember that if CGEN_INT_INSN_P then BUF is an int and thus the value
still needs to be converted to target byte order, otherwise BUF is an array
of bytes in target byte order.
The result is a pointer to the insn's entry in the opcode table,
or NULL if an error occured (an error message will have already been
printed).
Note that when processing (non-alias) macro-insns,
this function recurses.
??? It's possible to make this cpu-independent.
One would have to deal with a few minor things.
At this point in time doing so would be more of a curiosity than useful
[for example this file isn't _that_ big], but keeping the possibility in
mind helps keep the design clean. */
