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.

On 64-bit targets, we can skip the write barrier for Store nodes if the
input is ChangeInt32ToTagged, because the value being stored is
definitely represented as a smi then.

This is partially based on r21609 but that CL was incomplete.
Function name is still non writable so one has to use defineProperty
to change the actual value.

This required fixing the exports_ hash map to use the appropriate

Without this shortcut we generate one BooleanNot per JSUnaryNot with
number input, which is quite common in asm.js. These dead nodes then
survive until the late control reducer runs, and may prevent
optimizations in the mean time.

For now we just use the RawMachineAssembler, this will be changed
later to use the whole TurboFan pipeline.

This also adds a new VariableMode, IMPORT, which will be
used to do appropriate binding for Import-declared Variables.
Only named imports are handled for now. "import *" and default
import syntaxes have had their TODOs adjusted to match the new
code structure.

This reverts commit b57be748b1 and
disables the test/mjsunit/debug-clearbreakpointgroup.js because
BreakLocationIterator::ClearBreakPoint is already broken for unrelated reasons (see v8:3924).

We cannot yet detect use-before-declaration in general, because for that we'd
need to analyze the context when compiling. But we can detect an error case
where we first see a use, then a declaration.
For this, I also added end position tracking (needed for error messages) to
VariableProxy.
Note: the position naming is completely inconsistent: start_position &
end_position, position & end_position, pos & end_pos, beg_pos & end_pos, to name
a few. This doesn't fix all of it, but tries to unify towards start_position &
end_position whenever possible w/ minimal changes.

When a field type is a map, it is wrapped in a weak cell upon storing to the descriptor array.
Map::GetFieldType(i) does the unwrapping.

The new logic ensures that the error messages are the same in the
"import { <reserved word> }" and "import { foo as <reserved ord> }"
cases.
Also prepares ParseImportNames for returning both the import and local
names to ParseImportClause.

The FunctionLiteral returned from the parser for modules now has a MODULE_SCOPE,
instead of associating the module scope with a Block inside it. This makes
it easy to get at the ModuleDescriptor from the caller of Parse(), so I've added
a basic test that pokes at the scope and the descriptor. Expect more tests
in this vein.

Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. The bulk of the changes are to remove some
hard coded assumptions about heap page size within existing tests.
The remaining change is to use a larger heap page size for PPC linux
as this provides a performance benefit due to the larger memory page size.
