Description

[Christian Holler (:decoder)]

The following code asserts on TI tip (run with -n -m -a), tested on 64 bit:

function reportCompare (expected, actual, description) {}
function f()
{
  f(f, 0x09AA, 0x09B0, f);
}
{
  reportCompare ("outer", f(),
                 "Inner function statement should not have been called.");
}

Fix a known issue where we didn't reserve space for any frames we inlined.  This reserves some extra space before the end of the STACK_QUOTA which we can use for inlining, and checks when generating inline frames that we don't exceed the extra space.
