When using software completions, we have to prevent assembler to match
input and output operands of sqrtt/sqrtf insn. Add earlyclobber to
output operand to avoid unwanted operand matching.

* sysdeps/alpha/fpu/math_private.h (__ieee754_sqrt): Add
earlyclobber to output operand of sqrt insn.
(__ieee754_sqrtf): Ditto.
