[Rd] Access to integer value of BUILTINSXP/SPECIALSXP

[Saptarshi Guha]

After some reading, what i really need is something to give access to
PRIMNAME(obj).
Setting #define R_USEINTERNALS doesn't work and i'd rather not use
internals. Is the some exposed api call to get PRIMNAME?

Thank you
Saptarshi
