0fff64da8b Trigger a landmine on first-time landmine deployment.
Without this change, it is non-trivial to know during
runhooks, if a landmine was just triggered in a checkout
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.

bf3691ae88 Contribution of PowerPC port (continuation of 422063005) - PPC opt 2
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.
