Duplicate parameters are banned both overall in strict mode and also
in arrow functions. Our error message for both cases blamed strict
mode, which is confusing. This patch fixes the message to point to
arrow functions as a possible source as well.

This patch includes the following changes.
1, Enable the turbofan backend support for X87 platform. It depends on previous CL: 3fdfebd26.
2, Enable the test cases which are disabled because turbofan for X87 was not enabled.

The strong-object-set-proto test cases will throw one expected exception
and the exception message should include the source position in the JS
file. But crankshaft compiler does not generate the source position for
it when creating the flow graph by default. The source position information
is always zero. So it failed when comparing with the reference file.
If we use crankshaft compiler on IA32 platform to run this test case, it
has the same failure.
we will open these test case for x87 once turbofan for X87 is enabled.

A mistake in a recent CL has messed up the error messages for strong object

This makes the compilers agree on the source position of a message
generated by "throw new Error()", it points to the beginning of the
throw directive.

This commit is a precursor to making lazy arrow function parsing use
similar logic to function(){} argument parsing.

The ES6 grammar forbids the initialization of variable declarations in IterationStatements.
This CL will report `for (var x = y in z)` as a SyntaxError in strict mode (as done in JSC). It is possible that this could break sites in sloppy mode, and so that change can wait.

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.

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.

Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.
Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

This CL fixes tests that no longer valid and also fixes two issues:
1. 'super()' in non derived constructors.
2. Failure to step into derived constructors.

Replace the 'unable_to_parse' key used in three places with three difference keys.
Provide three more informative and less ambiguous error messages in place of 'Parse error'.
Add three test/message cases to cover the new messages.
