ia64: update abilist

ia64: update abilist

For the most part, these are adding symbols from newer glibc releases that
should have been added to ia64 in the first place, but no one noticed.

There were also adding symbols from older versions, but that appears to be
an oversight in the old abilist files where the ia64 tuple wasn't added to
the symbol block.

A few symbols did get deleted, but that looks normal as no other arch has
them, and comparing to an old glibc-2.7 build, things have been this way
for quite a while.

After this, `make check-abi` now passes for ia6.
