We were emitting this at global scope (not in Globals). That would lead
to errors about the variable needing to be in the constant address
space. (You can see the result in ConstArray.metal - the old code was
invalid). Also, we were already making references use _globals, so the
code was double-wrong (or half-right, depending on your perspective).
After the core change, writeVarDeclaration was only used for local
scope, and writeModifiers never used the 'globalContext' parameter.
The removal of finishLine() changed every test output, unfortunately.

This can eliminate const variables which have been completely folded
away, unnecessary synthetic variables created during codegen/inlining,
or code that simply didn't need to exist at all.

I ran into an issue in an upcoming CL which generated a particularly
ugly switch statement:
switch (x) {
default:
discard;}
So I cleaned this up, and while resolving this issue, managed to improve
a bunch of existing codegen as well. The formatting change has been
split out to a separate CL since it impacts so many golden outputs.
