Fix for issue 4638 in bitmap builder.
...
- Check for maximum size of byte offset and fatal out if it is larger.
- Convert some of the InRange asserts to actual checks.

Give a length field to stack bitmaps.
...
The bitmaps describing the stack have an explicit length field. It is now
an assertion failure to read bits outside the length --- they are no longer
assumed to be false.
Also remove an unused method and simplify the implementation of
BitmapBuilder by removing an embedded member that was always referred to via
a pointer.

Make stackmaps store their actual length.

This allows stackmaps with varying lengths in the same function, necessary
for the way we plan to support bitmaps for saved live registers.

Change the zone allocation api.
...
Instead of passing a size in bytes to the allocation function, we now
have a templatized Alloc function:
zone->Alloc<Type>(len)
This is better for security, as we can check for integer overflow in
the size computation before performing the allocation. Before, we
often failed to check this.

Fix an off-by-one error in the stack frame iteration.
...
When using a stackmap, we mapped stackmap index 0 to the code slot in the
frame. This code is still unused, but judging from the test the intent is
to map index 0 to the first local slot in the frame.

Resubmit change 6302 after fixing the compiler warning on older GCC compiler versions:
...
Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.
