Bad scenario:

- Enter a binop IC miss handler from optimized code object C from call
  site S,

- From the binop IC, invoke arbitrary javascript that lazy deopts C,
  so all relocation info is nuked and replaced with lazy deopt entries'
  reloc info. In particular, there is no reloc info for S.

- Still from the arbitrary JavaScript, make IC target's code object move.
  Note that the call site S is not updated.

- Return to the miss handler and inspect the IC's target. This will try
  to get the target from S, but that is a potentially invalid pointer.

It is quite possible that we will have to do a similar fix for other ICs,
but we will have to find a reliable repro first. I am not submitting a
repro here because it is quite long running and brittle (it
relies on code compaction happening while in the binop IC).

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.

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.

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 didn't create a .landmines file yet.

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.
