Fix memory leak in parser tests 
The `arena` instance being used bythe parse tree was valid and
pointed to valid memory, but existed as a local variable inside the
stack frame of the `parse` function (the `const arena`), which was never
stored anywhere before leaving the scope.

This meant that code above the `parse` function saw a valid instance of
an `ArenaAllocator` that pointed to the same backing memory, but didn't
posess any of the local state built up after the call to `parseRoot`,
basically the caller saw an empty arena.

This meant that when `deinit` was called, it saw an Arena with 0
allocations in it's `buffer_list` and wasn't able to destroy any of the
memory.  This caused it to leak and caused FailingAllocator to balk.

The fix is to make sure the parse tree is using the same instance of
ArenaAllocator as is reported up the call stack, the one inside the
`Tree{}` object.  I'm not sure why that field is marked with a comment
to remove it, as it's used by the `std.ast.Tree.deinit()` function, but
this change seems to solve the problem.

stage2 translate-c: implement functions with no prototype 
stage1 translate-c actually has this wrong. When exporting a function,
it's ok to use empty parameters. But for prototypes, "no prototype"
means that it has to be emitted as a function that accepts anything,
e.g. extern fn foo(...) void;

The *Mem variants cannot return EndOfStream and are generally unsafe to

Proper order of checks, try both the variants and make sure they return
the same error/result.
