This adapts the debugger so that the first break event starting the
stepping process can come from optimized code. TurboFan supports a
debugger statement and hence can be the top-most frame whenever the
Debug::HandleDebugBreak handler is triggered.

The root cause for the bug is that the positions assigned to desugared
code was inconsistent with the source ranges of block scopes.
Since the fact that the position is assigned causes the debugger to
break at the parser-generated statement, the fix is to remove positions
from those nodes that we do not want to break on.
The CL also teaches Hydrogen to tolerate these cases.

The test demonstrates a bad interaction between arguments object
materialization, escape analysis and exception handling.
We can return a wrong arguments object if we materialize arguments
object (using f.arguments) and then throw around f's frame so that f
does not clean up the materialized frame information (see the
MaterializedObjectStore in deoptimizer.h/.cc). If we enter another
function that has the same frame pointer and request an arguments object
of (or lazily deoptimize) that function, we can get the materialized
object of the original function.
We should clean up the materialized object store when we unwind the
stack.

Contribution of PowerPC port (continuation of 422063005,
817143002,866843003, and 901083004). This patch updates
the ppc directories to make them current with changes in
common code as of today.
We had to exclude the test test-serialize/SerializeInternalReference
until we agree on the right way to add those changes for PPC as
outlined in the description in the google doc provided earlier.
We also had to exclude a couple of other tests due to new
failures seen since the last uplevel. We excluded as opposed
to waiting until we could investigate to maximize the chance
of getting PPC compiling in the google repos before new
breaking changes are made.
I'll note that before applying any of our changes the
mozilla part of quickcheck was already broken when using
the lastest repo content so I had to run without that

Internal references are absolute addresses into the instruction
stream. Turn them into relative addresses when serializing and
back when deserializing to keep them valid.

Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.
Subsequent patches will cover:
- remaining optimizations for PPC
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
- incremental updates required to ppc directories due to platform specific changes made
in google repos while we complete the above steps.

The approach taken in this CL is to incrementally move toward the
currently-specced version of modules in ES6. The biggest change in this
patch is separating the parsing of modules from the parsing of scripts,
getting rid of the 'module' keyword and thus disallowing modules-in-scripts
as well as modules-in-modules.
The syntax supported by import/export declarations has not yet been significantly
changed, with the major exception being that import declarations require a string
as the 'from' part.
Most of the existing tests have been disabled, with a first new test added
in cctest/test-parsing.
