cf50c5e27c Handle exceptions thrown while parsing lazy functions for inlining.
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.

82cdd48b2f Fix a bug in deoptimization after logical expressions in an effect context.
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.

6b4ff18b5b Properly process try/finally blocks.
In some circumstances, try/finally block can actually catch the exception:

function f() {
  try {
    throw 42;
  } finally {
    return 0;
  }
}

Therefore when propagating exception to v8::TryCatch, we must be sure
there is no try/finally blocks as well.

When bulding the messages we should be more conservative and expect that
any v8::TryCatch with no JS try/catch in between can potentionally
be the right exception handler.

Plus various minor refactorings.

that a configurable but non writable property can have its value
changed with Object.defineProperty (because the same thing can be

performed and value property of the descriptor is set to undefined if caller doesn't
have proper access.  For JS accessors both v8::GET_ACCESS and v8::SET_ACCESS are checked
and affect if getter and setter would be stored in the descriptor.

f1149734fc Partial fix for V8 issue 1079.
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

Fixes JS portion of DefineOwnProperty when there is
an existing property and the new descriptor is generic.

Makes code follow spec steps more closely.

Fixes typo for check for unchanged enumerable in step 6.

Adds regression tests.
Fixes errors in object-define-property test

Don't normalize the JSGlobalProxy. Gets webkit http/tests/security/xss-DENIED-defineProperty.html working.

32a631d8bc Compare JSObjects by identity immediately.
When invoking EQUALS JS builtin, 1st argument is passed as a receiver and
if it's a global object, it gets overwritten with global proxy object and
thus one gets incorrect results.

93f8e3d821 Temporary disable comparison of optimizability of code objects in some cases.
With crankshaft, a code object can change its optimizability: it can start as
optimizable code object, but later we can find out it was a bad idea to
optimize it.  Alas, currently we don't have a proper event to communicate
this back to logger.  Hence we temporary allow a code object to be viewed
as optimizable judging from logs while being unoptimizable judging from
heap traversal.

471c0d2983 Avoid callbacks to user code during error formatting in a couple of
other situations.

Do not use overwritten Object.prototype.hasOwnProperty and
Array.prototype.pop. Do not use split and join in the error formatting
implementation. They are too big to control and their generality is
not needed.

4e7ddab6dc Fix a bug in the placement of minus-zero checks and in GVN.
1. The placement of checks for negative zero has to be computed after
all conversion instructions have been inserted. I separated the code
into its own phase.

2. GVN need to take instruction flags into account when comparing
instructions for redundancy.
