On x86-64 allow JSImmediate to encode 64-bit double precision values.
This patch only affects builds that set USE(ALTERNATE_JSIMMEDIATE).
- Updates the implementation of JSValuePtr
- and JSImmediate:: methods
that operate on neumeric values to be be aware of the new representation.
When this representation is in use, the class JSNumberCell is redundant
and is compiled out.
The format of the new immediate representation is documented in JSImmediate.h.
