tcg-hppa: Fix broken load/store helpers

The CONFIG_TCG_PASS_AREG0 code for calling ld/st helpers
was not respecting the ABI requirement for 64-bit values
being aligned in registers.

Mirror the ARM port in use of helper functions to marshal
arguments into the correct registers....

tcg/optimize: fix end of basic block detection

Commit e31b0a7c050711884ad570fe73df806520953618 fixed copy propagation on
32-bit host by restricting the copy between different types. This was the
wrong fix.

The real problem is that the all temps states should be reset at the end...

revert "TCG: fix copy propagation"

Given the copy propagation breakage on 32-bit hosts has been fixed
commit e31b0a7c050711884ad570fe73df806520953618 can be reverted.

tcg: mark set_label with TCG_OPF_BB_END flag

set_label is effectively the end of a basic block, as no optimization
can be made accross it. It was treated as such in the liveness analysis
code, but as a special case.

Mark it with TCG_OPF_BB_END flag so that this information can be used...
