Message:

[JSC] The destination of Sqrt should be Def, not UseDef
​https://bugs.webkit.org/show_bug.cgi?id=154086

Reviewed by Geoffrey Garen.

An unfortunate copy-paste: the destination of SqrtDouble and SqrtFloat
was defined as UseDef. As a result, the argument would be interfering
with everything defined prior.
