[dev.typeparams] cmd/compile: add dictionary argument to generic functions
When converting from a generic function to a concrete implementation,
add a dictionary argument to the generic function (both an actual
argument at each callsite, and a formal argument of each
implementation).
The dictionary argument comes before all other arguments (including
any receiver).
The dictionary argument is checked for validity, but is otherwise unused.
Subsequent CLs will start using the dictionary for, e.g., converting a
value of generic type to interface{}.
Import/export required adding support for LINKSYMOFFSET, which is used
by the dictionary checking code.
