I noticed that there are undocumented functions mpn_addlsh_n and
mpn_rsblsh_n in GMP, and I was wondering if there is any possibilities
to add corresponding mpz functions in the lines of:
mpz_addmul_2exp(mpz_t rop, const mpz_t op1, mp_bitcnt_t op2)
Set rop to rop + op1 times 2 raised to op2.
Would this be possible? If not, would it be possible to document and
"uncover" these functions so that one can utilize these mpn functions
These functions are optional and used internally only if available.
Since they might not be in every GMP build they cannot be made
