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.
