The '<tt>llvm.sqrt</tt>' intrinsics return the sqrt of the specified operand,
returning the same value as the libm '<tt>sqrt</tt>' functions would. Unlike
<tt>sqrt</tt> in libm, however, <tt>llvm.sqrt</tt> has undefined behavior for
negative numbers (which allows for better optimization).
negative numbers other than -0.0 (which allows for better optimization, because
there is no need to worry about errno being set). <tt>llvm.sqrt(-0.0)</tt> is
defined to return -0.0 like IEEE sqrt.
