Re: Fix ldbl-96 hypotl of subnormals (bug 15529)

Examining the listed LSB failures showed bug 15529, ldbl-96 hypotl
giving incorrect results for subnormal operands because, when
multiplying by 2^16382, it actually multiplied by an invalid value
with the high bit of the mantissa (that is explicit in the ldbl-96
format) not set.  This patch fixes the code to use a correct
representation of 2^16382.  Tested x86_64 and x86.

ok, thanks!
