[Qemu-devel] [PULL 20/20] target-arm: Delete unused iwmmxt_msadb helper

[Peter Maydell]

The iwmmxt_msadb helper and its corresponding gen function are unused;
delete them. (This function appears to have never been used right back
to the initial implementation of iwMMXt; it is identical to iwmmxt_madduq,
and is presumably an accidental remnant from the initial development.)
