[runtime] Sanitize %NewClosure runtime entries.

[runtime] Sanitize %NewClosure runtime entries.

There are now two runtime entries %NewClosure and %NewClosure_Tenured,
with the same signature (one parameter, the SharedFunctionInfo, and the
context of the caller).

Also remove the HFunctionLiteral special case instruction from Crankshaft,
as HCallWithDescriptor with FastNewClosureStub or HCallRuntime with
either %NewClosure or %NewClosure_Tenured can easily do that for you.

Also remove the redundant context parameter from the JSCreateClosure
operator, because every JS operator already takes a context input.
