[AArch64] Cortex-A57 FDIV/FSQRT scheduling fix (W-unit)
According to the Cortex-A57 doc, FDIV/FSQRT instructions should use F0 unit
(W-unit in AArch64SchedA57.td, the same as cryptography instructions),
not F1 unit (X-unit in td, like ASIMD absolute diff accum SABA/UABA).
This patch changes FDIV/FSQRT scheduling declarations to use A57UnitW
instead of A57UnitX. Also, latencies for those instructions are
corrected.
Patch by Andrew Zhogin.
