Fix crash in QtScript/JSC stack allocator on Symbian
The reserved (virtual) size of the chunk is not necessarily a
multiple of the "pool" size (the physical growth increment).
The reserved size is only rounded up to a multiple of the page
size (4K), not the pool size (64K).
This meant that the commit of the _last_ part of the chunk could
(and did) fail, because we tried to commit 64K while only a size
<64K was remaining.
Detect this case and reduce the requested size accordingly.
Also add a call to CRASH() in case Commit() returns an error,
to avoid obscure crashes in JSC at a later point (grow() must
not fail).
