megasas: fix guest-triggered memory leak

If the guest sets the sglist size to a value >=2GB, megasas_handle_dcmd
will return MFI_STAT_MEMORY_NOT_AVAILABLE without freeing the memory.
Avoid this by returning only the status from map_dcmd, and loading
cmd->iov_size in the caller.

libqtest: handle zero length memwrite/memread

Some recently added tests pass a zero length to qtest_memwrite().
Unfortunately, the qtest protocol doesn't implement an on-the-wire
syntax for zero-length writes and the current code happily sends
garbage to QEMU. This causes intermittent failures.

It isn't worth the pain to enhance the protocol, so this patch
simply fixes the issue by "just return, doing nothing". The same
fix is applied to qtest_memread() since the issue also exists in
the QEMU part of the "memread" command.

tcg/i386: Allow bmi2 shiftx to have non-matching operands

Previously we could not have different constraints for different ISA levels,
which prevented us from eliding the matching constraint for shifts.

We do now have to make sure that the operands match for constant shifts.
We can also handle some small left shifts via lea.
