Reserve code range block for evacuation.
...
If we run out of code range, then GC wouldn't be able to compact code space,
because it wouldn't be able to allocate a new page. This can cause code space
fragmentation and OOM crashes.

Fix for bug 429168, PdfJs regression. We pay a very high cost for AllocationResult being a > kPointerSize struct. This can be avoided by using Smis to indicate failure with retry spaces.

Add support for a target new space size
...
When this flag is set, we will commit additional pages up until the
target size before doing a scavenge.
I made sure that all tests pass when a target size of 16MB is set.

Add a getter for the address and size of the code range to the pulic API
...
Since the x64 backend currently doesn't emit ABI compliant code, it is
not possible to unwind the stack. During Win64 SEH this will cause the
exception handling to abort, and not even call the unhandled exception
handler. Embedders are advised to install a custom unwind callback using
RtlInstallFunctionTableCallback for the entire code range to catch
unwind attempts for exception handling.
