8b33567fd3 Simplify error message logic in ParseImportNames 
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.

238ad54d0f Move compilation error handling into a separate class. 
In addition to Parser, other phases (such as scope analysis) need to handle
compilation errors in the future. PendingCompilationErrorHandled takes care of
error handling in a unified way.

b00ff50d52 Clobber output directory on linux and mac after landmine. 
Xcode uses a different naming scheme for directories within
the xcodebuild directory. But it is safe to just delete
everything withing xcodebuild or out. Keep the soft clobber
for windows' build directory only, where subdirectories
follow the *release* and *debug* naming scheme.

that doesn't have the initial landmines script CL yet, i.e.
that didn't create a .landmines file yet.

1a8dc98cbf Fix up ParseProgram and ParseModule to do something sane with module scopes 
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.

89731cfbf8 Port chromium landmines script. 
This runs the landmines script as a gclient hook. It can
as such be used to clobber local checkouts when hooks are
run locally.

It is a softer version than chromium's landmines script, as
it only deletes directories in the output directory due
to compatibility with MSVS which has "build" hardcoded as
output directory in several places.
