8a7f1568c4 Ensure that we do a non-incremental GC before relying on weak handle callbacks. 
Previously, some tests failed when being run with a low GC interval. This was
caused by a switch of the GC to incremental marking mode, which in turn did not
fire any callbacks for weak global handles. Now we make sure that we run in
non-incremental mode, although via a slightly misleading GC flag.

We should probably review the uses of PerformScavenge() and gc() in our tests to
see if they actually mean "make sure our callbacks fired".

b8b50400d2 Inline builtin Math functions functions in more cases. 
Until now we only could inline as specialized HIR instructions when called
as a method (e.g. Math.abs)

It is very common practice to abbreviate calls to those functions by defining
a global or local variable like:

var a = Math.abs;
var x = a(123);

This change allows inlining them when called as a function (global or local).
