use a specific struct for asm operands
ASM operands have the following syntax:
[<ident>] "<constraint>" '(' <expr> ')'
For some reasons, during parsing this is stored
as a sequence of 3 expressions. This has some serious
disadvantages though:
- <ident> has not the type of an expression
- it complicates processing when compared to having a specific
struct for it (need to loop & maintain some state).
- <ident> is optional and stored as a null pointer when not present
which is annoying, for example, if null pointers are used internally
in ptr-lists to mark removed pointers.
Fix this by using a specific structure to store the 3 elements
of ASM operands.
