7bd3f1cc78 Fix fuzzer-discovered assertion with global variables.
Our analysis pass for checking if an expression is a constant-expression
would assert if the expression contained a TypeReference or a
FunctionReference. This could happen if you passed in an expression that
had not yet been type-coerced. This check seemed overly strict, so the
assertion has been removed (although such an expression will be reported
as 'not a constant expression').

This bit us in global-variable declaration, where we checked if a
global variable's initial-value expression was constant before coercing
it to the variable's type. This has also been reordered so the type-
coercion happens first. (Either order is now valid, but the type-
coercion related errors tend to be more detailed.)

842ee5bd8d Fix assertion when calling a built-in function at global scope.
The fuzzer invented a much more elaborate example, but I was able to
winnow it down to a simple otherwise-normal test case. This also fixes
a latent DSL bug; DSL functions were not updating the list of referenced
intrinsics, so the compiler might emit finished programs that called
built-in functions that didn't exist in the code.
