target-sparc: Fix -singlestep.

Single-stepping was not properly updating npc, resulting in some
instructions being executed twice. In addition, we were emitting
dead code at the end of the TB.

Fix both by teaching gen_goto_tb to avoid goto_tb for single-step...

target-sparc: Fix address masking in ldqf and stqf.

Use address_mask on both addr and addr+8 in both these routines,
rather than explicit masking with 0xffffffff.

Reformulate address_mask to return a result, rather than masking
a pass-by-reference argument....

target-sparc: Free instruction temporaries.

Rather than creating new temporaries for constants, use the
ones created in disas_sparc_insn. Remember the temps created
there so that they can be freed at the end of the function.

Profile data collected by TCG while booting sparc-test kernel:...
