This patch to the Go frontend implements better checks for constants
passed to the predefined function make. It gives an error for using
negative numbers, and when the length is larger than the capacity.
These are required by the language spec, but were never enforced by the
compiler until now.
Because of the efforts the Go frontend takes to avoid knock-on errors,
it was possible for some erroneous code to get through without an error
message. Specifically, code like v().NonexistentFunction() would not
produce an error when v was not a function. This patch fixes that
problem.
The Go language accepts an optional comma after an expression in a type
conversion. This is because type conversions can look like function
calls. The Go frontend was incorrectly rejecting these valid programs.
This patch fixes that. Bootstrapped and ran Go testsuite on
