Style cleanup of switches over Slot::Type in the nonoptimizing code
generator.
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.

Extend the maximum size map space
On 32-bit the maps are now aligned on a 32-byte boundary in order to encode more maps during compacting GC. The actual size of a map on 32-bit is 28 bytes making this change waste 4 bytes per map.
On 64-bit the encoding for compacting GC is now using more than 32-bits and the maps here are still pointer size aligned. The actual size of a map on 64-bit is 48 bytes and this change does not intruduce any waste.
My choice of 16 bits for kMapPageIndexBits for 64-bit should give the same maximum number of pages (8K) for map space. As maps on 64-bit are larger than on 32-bit the total number of maps on 64-bit will be smaller than on 32-bit. We could consider raising this to 17 or 18.
I moved the kPageSizeBits to globals.h as the calculation of the encoding really depended on this.
There are still an #ifdef/#endif in objects.h and this constant could be moved to globaks.h as well, but I kept it together with the related constants.
All the tests run in debug mode with additional options --gc-global --always-compact as well (except for a few tests on which also fails before this change when run with --gc-global --always-compact).

Fix a crash caused by garbage collection during generation of a
callback load (or keyed load) IC.
The problem was that the IC code calls a stub, which can allocate and

generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.
