The intention is to store enough scope information for the debugger to
handle stack allocation of block scoped variables introduced by
http://codereview.chromium.org/7860045/ .

This CL is based on
http://codereview.chromium.org/7904008/ .

dac0b853e1 Improve speed of Utf8Write by always flattening the string first and 
detecting the ASCII case.  Also rewrite Utf8Length to work on an
unflattened string.  Bug: http://code.google.com/p/v8/issues/detail?id=1665

2bbf3bbee7 Make native syntax an early error in the preparser. 
Previously the preparser always accepted natives syntax and let the
real parser throw the syntax error. In ES5, it should be an early error,
so the preparser must catch the error.
The perparser library does not expose parsing for natives syntax, it's
only used internally.

07c1c9ebc7 MIPS: small test-case fix for chaining of fixup position. 
Add nops to the branch-delay slots of the 'beq' and 'bne' instructions
used in the test-case. Having a branch instruction in the branch-delay-slot
of another branch is undefined on mips.

In regular code we avoid this by using the Branch() macro-instruction which
fills the branch-delay-slot with nop() automatically, unless the programmer
asks to use it (via USE_BRANCH_DELAY).

There is more info about branch-delay-slots on this page, and in the ISA
reference also on the page:

4084e698c3 Fixed a bug in the chaining of fixup position 
The ARM and MIPS assemblers had a bug where they did not handle the last element
in the list of code positions correctly during the fixup of offsets for forward
jumps. This happened when the first instruction contained a forward jump to a
label, and that label was used in a forward jump later, too.

Unified the code for Assembler::next on ARM and MIPS while we were there.

Added test cases, even for ia32/x64, which seem to be correct, even I don't
fully understand why... %-}
