as shift ,1 operands and imm operands that have sign-extended imm8 forms that

Bugzilla Bug#3. Not all instructions are parsed yet, so this is actually a
minor feature regression from the user side, but this commit lays the framework
for much easier additions of new assembler syntaxes and architectures. The
re2c tool is now used to generate the lexers, as it's much more flexibly
function-oriented than lex.
- nasm-bison.y is a repocopy+modify of nasm/bison.y.in.
- x86arch.h now includes all of x86-int.h

This is actually worthwhile; I found and fixed a few bugs/edge cases while
doing this.
