      [runtime] Drop FIRST/LAST_NONCALLABLE_SPEC_OBJECT instance type range. · aafc3e54
      Benedikt Meurer authored 
      The FIRST-LAST_NONCALLABLE_SPEC_OBJECT_TYPE range was accidentially used
in field type tracking, where we should check for JSReceiver instead
(there's no need to exclude JSProxy or JSFunction from tracking).

And the use in %_ClassOf was actually wrong and didn't match the C++
implementation in JSReceiver::class_name() anymore. Now it's consistent
again.

      [runtime] First step to sanitize regexp literal creation. · 09b44428
      bmeurer authored 
      This is the initial step towards refactoring the regexp literation
creation code to make it less obscure and more similar to the mechanism
we use to create array and object literals.  There's now a new runtime
entry %CreateRegExpLiteral with the same interface as the entries for
array and object literals, except that we still pass the flags as
string.

Instead of embedding the hand written native to clone JSRegExp instances
we now have a FastCloneRegExpStub, which behaves similar to the other
FastCloneShallowArrayStub and FastCloneShallowObjectStub that we already
had.

      [builtins] Sanitize the machinery around Construct calls. · 374b6ea2
      bmeurer authored 
      There's no point in collecting feedback for super constructor calls,
because in all (interesting) cases we can gather (better) feedback from
other sources (i.e. via inlining or via using a LOAD_IC to get to the
[[Prototype]] of the target).  So CallConstructStub is now only used
for new Foo(...args) sites where we want to collect feedback in the
baseline compiler.  The optimizing compilers, Reflect.construct and
super constructor calls use the Construct builtin directly, which allows
us to remove some weird code from the CallConstructStub (and opens the
possibility for more code sharing with the CallICStub, maybe even going
for a ConstructICStub).

Also remove the 100% redundant HCallNew instruction, which is just a
wrapper for the Construct builtin anyway (indirectly via the
CallConstructStub).

Drive-by-fix: Drop unused has_function_cache bit on Code objects.

      [crankshaft] Pass new.target to direct function calls. · e2bce9d3
      mstarzinger authored 
      This changes all direct function calls in Crankshaft to pass undefined
via the register expected to hold the new.target value. Note that the
register is still ignored by all callees for now.

This is a preparatory CL to allows us passing new.target in a register
instead of via a side-channel through the construct stub frame.

      [runtime] Drop redundant %CharFromCode runtime entry. · 2b4cb2a1
      bmeurer authored 
      The %StringCharFromCode and %CharFromCode runtime function perform
exactly the same task, so we need only one of them.

      [builtins] Introduce specialized Call/CallFunction builtins. · 7c3396d0
      bmeurer authored 
      Introduce receiver conversion mode specialization for the Call and
CallFunction builtins, so we can specialize the builtin functionality
(actually an optimization only) based on static information from the
callsite (this is basically a superset of the optimizations that were
available with the CallFunctionStub and CallICStub, except that these
optimizations are correct now).

This fixes a regression introduced by the removal of CallFunctionStub,
for programs that call a lot.
