By doing this we can make any number of decisions about code generation
during the prologue. For instance, we can decide whether or not to
reserve a register to hold the value of GUEST_BASE.
This fixes a latent bug in the two ppc ports in that GUEST_BASE was
being loaded as an immediate before the final value of GUEST_BASE is
computed.
This also fixes some register reservation problems I noticed in the
ia64 port, while trying to decide which register to use for holding
GUEST_BASE across the TB.

tcg-hppa: Load GUEST_BASE as an immediate.
tcg-ia64: Fix some register usage issues.
tcg-ia64: Load GUEST_BASE into a register.
tcg-ppc: Conditionally reserve TCG_GUEST_BASE_REG.
