Ahmed Bougacha e8d0c4ccea [ARM][FastISel] Use TST #1 instead of CMP #0 for select. ...

Since r234249, i1 are sext instead of zext; because of that, doing
"CMP rN, #0; IT EQ/NE" isn't correct anymore.

"TST #1" is the conservatively correct alternative - the tradeoff being
that it doesn't have a 16-bit encoding -, so use that instead.
