tcg-ia64: Fix some register usage issues.
(1) The output registers were not marked call-clobbered, even though
they can be modified by called functions.
(2) The thread pointer was not marked reserved.
(3) R4-R6 are call-saved, but not saved by the prologue. Rather than
save them, mark them reserved so that we don't use them.
