Allow a target assembly parser to do context sensitive constraint checking
on a potential instruction match. This will be used, for example, to handle
Thumb2 IT block parsing.

when AVX mode is one. Otherwise is just more work for the type
legalizer.

There is no need to maintain a set to keep track of variables that use location expressions. In such cases, AT_location attribute's value will be a label.

No need for it to be redefined as part of every derived target asm parser
class.

Enforce the constraint that Rt must be even on LDRD/STRD instructions in ARM mode.  Update tests to reflect this fact.

When a variable is inlined multiple places, abstract variable keeps name, location, type etc.. info and all other concreate instances of the variable directly refers to abstract variable.
