ebebcae4c2 Allow esi to be an allocatable register on IA32.
Make esi available to the register allocator rather than dedicating it
permanently to the context.

The context is still passed in register esi to JavaScript and to the runtime
as part of the calling convention.  Because some stubs might end up calling
JS or the runtime, it is also conservatively passed to stubs.

Roughly half the calls have been modified to use the context as an input
value in fixed register esi.  The other half are marked as calls or deferred
code so esi is spilled and can be explicitly set.

It is no longer necessary to restore the context to esi after a call that
might change it.

32cd13ebf1 Remove the redundant load on every context lookup.
There was an unnecessary load on every statically-resolved context lookup.
Remove it.

This revealed a hidden bug in const initializers inside 'with'.  They claim
to be statically resolved (having slot type CONTEXT) but they occur in a
spot where the runtime context chain and the static scope chain do not
agree.  This is fixed by special casing const initializers in the backend.

161d631b5e Change ARM exit frame layout and alingment handling
Change the ARM exit frame to have the same layout as the IA32 exit frame. This basically re-arranges the order of fp and sp and changes the sp location of the entry frame to hold the sp used by the gc and not the sp for popping the arguments. This removes the option of tearing down the frame and returning using one ldm instruction.

The main motivation for this is to avoid pushing an alignment word before generating the entry frame. The GC handling of optimized frames process the registers pushed as part of a safepoint and asumes that these are at the top of the frame, so if an alignment word is pushed this processing will be one off.

The alignment handling in the C entry stub have also been simplified. Now the value of lr is stored to a stack slot already reserved avoiding pushing it and keeping track of "frame skew".

This does result in more instructions in the exit frame on ARM, but we can look into improving this later.

426f13e084 Fix GC issue in instanceof stub
The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC.

Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago).

This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.

4c6f79ecec Fix crashes during GC caused by partially initialized objects. The
inline allocation code used the expected number of properties to
calculate the number of inobject properties for an object instead of
getting the actual number from the initial map.

It is safer to use the inobject property count from the initial map in
any case because that is the amount the instances will get. I think
this disconnect got introduced when adding shrinking of objects.

Unfortuntely I haven't been able to create a simple reproduction for a
test case but this fixes the webpage that exhibits the crash. I'll see
if I can create a reproduction tomorrow.
