74d49a1e7e ARM64: Preserve x8 and x9 when necessary. 
Fix a couple of places were x8 and x9 are excluded from lists of saved
registers. These are caller-saved registers, so C code can corrupt them.

x8 and x9 were originally reserved for debug code in the ARM64 port, so
we didn't bother preserving them, but they are now normal allocatable
registers.

2e9902b22a Partially fix semantics of Array.push() 
Semantics of elements accessors are now preserved in all optimized code paths
through Array.push(). Previously it was possible to have inconsistent behavior
between optimized and unoptimized code, and there were cases where element
accessors were completely ingored.

8aa93f2443 Bugfix: A TransitionArray can disappear during copy. 
During handlification of TransitionArray code, an error was introduced
in TransitionArray::CopyInsert because after creating a copy of a
TransitionArray, it may be that the array disappears during GC
because it is modified during the marking of the owning map.

5bddec047d Do not use ranges after range analysis. 
Due to the SSA vs. SSI difference, we are only allowed to use the
flags computed during range analysis, not the ranges themselves. For
the case at hand, there is no such flag, so the condition is simply
remvoed.

4620ae5cf1 Fix symmetry of Maybe() predicate. Fix bug in NowContains() predicate. 
Add tests for TypeImpl::Of(), TypeImpl::NowOf() and
TypeImpl::NowContains(). Improves the implementation of
TypeImpl::NowIs() to match that of TypeImpl::NowContains().

Mark test-types with NO_VARIANTS to speedup testing, since
the variants do not affect the type system at all.

Also improve test coverage for types.

e93599c502 ARM64: Put all simulator trace on the same stream. 
The simulator can trace to a specified stream, typically stderr or
stdout. However, several messages (such as ASM_LOCATIONs) were printed
only to stdout. As a result, they often ended up out of order with
respect to the instruction trace. This patch causes all simulator output
to go to the same stream.
