0ff690b370 Fixed a long-standing TODO: Removed a few *-incl.h #includes from isolate.h. 
ZoneAllocationPolicy::New is not inlined anymore because this pulls in far too
much stuff and doesn't really make any measurable performance difference. And
no, the #includes are still not in alphabetical order... ;-)

c71cf782e8 Drastically reduce the transitive dependencies of jsregexp.h, making it (almost) 
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.

5528ce7057 MIPS: Cleaned up calling-related methods in the assembler. 
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.

4145dded9a MIPS: port Introduce code flushing of RegExp code. 
Ported r8532 (c9db503)

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.

57760b8275 Make preparser detect duplicate parameters and object literal properties. 
This is a fix and reapply of r8516 with some comments addressed and more
tests added.
The difference from r8516 is that canonicalization of number literals is
no performed using the same methods as in v8, to avoid false positives/negatives
when detecting duplicates.
