true.  The rules are:

1. Heap::AllocateRaw can normally handle allocation requests in new
   space even when always_allocate() is true.  It properly retries
   failed allocation in the second 'retry' space.

2. Heap::Allocate can normally handle allocation requests in new
   space.

3. We only need to check always_allocate() when explicitly requesting
   allocation in new space via Heap::new_space().AllocateRaw().

4. The exception to these rules is fixed arrays with size such that
   MaxObjectSizeInPagedSpace < size <= MaxObjectSizeInNewSpace (ie,
   those that will be allocated in new space and promoted to large
   object space).  They cannot be allocated in new space via
   Heap::Allocate or Heap::AllocateRaw, because the retry logic does
   not know to allocate extra remembered set bits when retrying in
   large object space.

The Slot::Type enumeration has four values.  It should never be
necessary to use a default to handle the case of a value out of range
of the enumeration.  Doing so silences a useful warning when one of
the enumeration values is actually forgotten or when a new enumeration
value is added.

If a function contains more than a certain number of locals (IA32: 9, X64: 6, ARM: 4) 
a loop for initializing the locals with 'undefined' is more compact. 
For less locals we unroll that loop by emitting a sequence of push instructions.

The runtime function checks if it needs to create a boilerplate
object or if it can clone from an existing boilerplate.

This is already done in the top-level compiler.

to floating point and then converting back we convert directly to a
32 bit integer.  In addition the bit twiddling implementation of float-
to-integer conversion has been ported from ARM.  Testing has shown that
this runs faster than the x87 or SSE3 rounding instructions.  This change
is IA32 only.  There may be a smaller benefit from doing the same on x64.
