Martin Jansa 27c5e756a2 sysdeps/ieee754: prevent maybe-uninitialized errors with -O [BZ #19444] 
With -O included in CFLAGS it fails to build with:

../sysdeps/ieee754/ldbl-96/e_jnl.c: In function '__ieee754_jnl':
../sysdeps/ieee754/ldbl-96/e_jnl.c:146:20: error: 'temp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      b = invsqrtpi * temp / sqrtl (x);
          ~~~~~~~~~~^~~~~~

  b = invsqrtpi * temp / sqrt (x);
      ~~~~~~~~~~^~~~~~

Build tested with Yocto for ARM, AARCH64, X86, X86_64, PPC, MIPS, MIPS64
with -O, -O1, -Os.
For AARCH64 it needs one more fix in locale for -Os:
https://sourceware.org/ml/libc-alpha/2018-09/msg00539.html

	[BZ #19444]
	* sysdeps/ieee754/dbl-64/e_jn.c (__ieee754_jn): Use
	__builtin_unreachable for default case in switch.
	(__ieee754_yn): Likewise.
