95145fa826 Ship ES2015 sloppy-mode const semantics
This patch moves the semantics of 'const' in sloppy mode to match those
in strict mode, that is, const makes lexical (let-like) bindings, must
have an initializer, and does not create properties of the global object.

a01b45df58 Fix a number of tests that incorrectly used assertUnreachable.
Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:

try {
  shouldThrow();
  assertUnreachable();
} catch(e) {
}

Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.

f54b7767c6 Implement fast load and call of arguments in the presence of eval.
Load the arguments object from the context if there are no extensions
objects on the way. Then load the argument with a keyed load ic.

856135af42 Implement fast calls of functions in the presence of eval (if the eval
calls do not introduce new bindings).

The infrastructure is already in place for fast loads from context
slots in the presence of eval.  This change simply uses that
infrastructure for calls as well as loads.

b4b5e3ca95 Not sure what happened, but my revert did not get everything out. Fixing the problem instead. The issue was using tmp instead of context in two places.

a09832ab76 Optimize loads from variables that might be shadowed by variables
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.
