The Hydrogen graph translation does not build a branch for unary negation in
an effect context, so the baseline compiler should not do so either.

We leave room for all registers on the stack so we have to add a bit.

This is not nicely factored and I need to do that. This will fix the breakage and I
will fix the rest on Monday.

Object.preventExtensions can currently be used cross-domain. With this
change we follow firefox (IE9 has our current behaviour). In addition
this includes a regression test for 1027 and access tests for
Object.seal and Object.freeze.

Call accessors in the global object prototype when initializing global
variables. Function declarations are special cased for compatibility
with Safari and setters are not called for them. If this special
casing was not done webkit layout tests would fail.

Make the declaration of global const variables in the presence of
callbacks a redeclaration error.

Handle const context slot declarations conflicting with a CALLBACK as
a redeclaration error. That is, unless it is on a context extension
object which is not a real object and therefore conceptually have no
accessors in prototype chains. Accessors in prototype chains of
context extension objects are explicitly ignored in SetProperty.

The baseline compiler does not materialize a value for expressions of
the form !expr in an effect context so the graph translation should
not produce such an environment, otherwise we risk targeting it by
deoptimization.

We currently leave the exception as pending without returning a Failure::Exception() value. This is either caught immediately if running with --debug-code, or caught later by an assert in debug mode.

This change makes the pending exception be cleared before returning from the failed optimization attempt.

When deoptimizing to after an expression of the form (expr0 || expr1)
or (expr0 && expr1) in an effect context, the unoptimized code could
incorrectly see the value of the expression.

Handle the short-circuit binary operators specially in effect contexts.
This fixes the issue and will generate better code when the left
subexpression is boolean-valued.
