Hi all,

In continuation of patch [1/2]...
We can use the vector forms of the vcvt{a,p,m} instructions to vectorise
the l{round, ceil, floor}f functions.
Builtins are added and the TARGET_VECTORIZE_BUILTIN_VECTORIZED_FUNCTION
implementation is updated to wire up the vectorised forms of these
functions to the midend.

Bootstrapped and tested on arm-none-linux-gnueabihf.

Ok for trunk?

Ok - thanks.

Ramana

Thanks,
Kyrill
