compiler: remove LHS/RHS context determination for var exprs
Remove the code that determined LHS/RHS context for var expressions
(was needed previously for some instances of the back end). LHS/RHS
context is computed by the back end in all cases, so no need to have
this code in the front end any more.
Reviewed-on: https://go-review.googlesource.com/77510
* go-gcc.cc (var_expression): Remove Varexpr_context parameter.
