  target-sparc: Don't compute full flags value so often

Avoid speculatively computing flags before every potentially trapping
operation and instead do the flags computation when a trap actually
occurs.  This gives approximately 30% speedup in emulation.

  tcg-sparc: Fix setcond

The set of comparisons that can immediately use the carry are LTU/GEU,
not LTU/LEU.  Don't swap operands when we need a temp register; the
register may already be in use from setcond2.

  tcg-sparc: Drop use of Bicc in favor of BPcc

Now that we're always sparcv9, we can not bother using Bicc for
32-bit branches and BPcc for 64-bit branches and instead always
use BPcc.

New interfaces allow less direct use of tcg_out32 and raw numbers
inside the qemu_ld/st routines.
