Declaration of const lookup slots would trigger an assertion if there was a
setter somewhere in the prototype chain, and that setter was shadowed by a
non-readonly data property also in the prototype chain.

If map has an empty DescriptorArray we have to set map_or_index_field to NULL otherwise we will
reset iteration state for a previously visited map in the transition tree which has a non-empty
DescriptorArray. This might result in visiting the same map several times.

architecture-independent.

jsregexp.h is itself included transitively quite a lot, and by getting rid of 19
of its dependencies (which even included things like src/cpu.h, the various
assemblers, etc.), the recompilation behaviour is a bit less funny than it was.

Patterned after r8482, Cleaned up calling-related methods in the ARM assembler.

On MIPS I completely refactored the Jump and Call methods.
All the Jump and Call macro helpers have been replaced with overloaded functions
(matching the ARM version) and using default parameter values where possible.
The previously mostly-unused CallSize function is utilized as well (same as on ARM).
The unused Jump(Operand, ...) and Call(Operand, ...) versions have been completely removed.
I also removed the Jump(BranchDelaySlot, ...) and Call(BranchDelaySlot,...) methods as
they were unused and declaring them would either result in a lot of unused code or the
previously experienced macro-hell. The only exception to this is for Ret() where the
branch delay slot is often used.

This fixes the failing debug tests for example cctest test-debug/DebugStepFor.

Also avoid that calling Debug::IsBreakAtReturn causes a full doptimization when there are no break points set. The full deoptimization is caused by Debug::IsBreakAtReturn calling Debug::EnsureDebugInfo which will assume that a break point is now set.

We did not properly combine the property names from the parameter map
and the arguments backing store.  They could overwrite each other and
be unsorted.

Also fix an unrelated bug: deleting from a dictionary-mode arguments
backing store could corrupt the parameter map.

Original commit message:
Due to issues relating mostly to chrome extensions we have lately been
running into OOMs that are caused by our executable space running
out. This change introduces flushing of code from regexps if we have
not used the code for 5 mark sweeps.
The approach is different from the normal function code flusing. Here
we make a copy of the code inside the data array, and exchange the
original code with a smi determined by the sweep_generation (a new
heap variable increased everytime we do mark sweep/compact). If we
encounter a smi in EnsureCompiled we simply reinstate the code
object. If, in the marking phase of mark sweep, we find a regexp that
already have a smi in the code field, and this is more than 5
generations old we flush the code from the saved index.

This patch enables insertion of To{Slow,Fast}Properties around a group
of assigments to the same object even when they are put in a block
(e.g. try-catch, if, etc.). Catching exceptions and disabling parts of
code based on some config vars is rather common in top-level code.
