On mips64, remove unused JumpLabelToJumpRegister(). On mips, rename
it appropriately (it's still used there for JR->J optimizations).

This keeps the length of the context chain tracked by the environment
in sync even for local control flow commands. It removes the need to
guess the correct chain length at Environment::Merge points.

Currently, this doesn't really help to generate better code,
nevertheless this is the right thing to do. When our type system(s)
are fixed, this should avoid falling back to floating point operations
in various cases.

In ES6 Object.getOwnPropertyDescriptor should call ToObject, which
means that primitive values will return descriptors from the wrapper.

The removed assertion consistently passes not because the invoked
`close` method internally throws a `TypeError` but because the `close`
method does not exist. The ES6 specification does not define a `close`
method on the GeneratorPrototype, so this test is a tautology.

The modified assertions targeted the property descriptor for the
template object's first "cooked" value. The code immediately preceeding
these statements asserts these values.
Update the assertions to instead target the property descriptor for the
template object's first "raw" value (which are otherwise untested).

This reverts commit 992751d0dc.
The final spec for Object.getPrototypeOf calls ToObject on the
parameter, which means that it should only throw for null and
undefined. For other non object values the prototype of the wrapper
should be used.
Difference from last time: Updated .status and will disable Blink
side tests as needed.
