from x86/aasmcpu to aasmtai and (new) aasmsym, so that when they're
finished they're available for all targets
* added dummy implementation of tai_cpu_abstract.pass1 and pass2 so there
are no more hundreds of warnings on non-x86 about constructing taicpu
instances with abstract methods

Contains abstract assembler instructions for all processor
|
|
types, including routines which depend on the symbol table.
|
|
These cannot be in aasmtai, because the symbol table units
|
|
depend on that one.

* Portions of this code was inspired by the NASM sources
