[PATCH] D103634: [BitcodeWriter][PowerPC] Avoid clearing lower bits for ppc_fp128 NullValues

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Constant::isNullValue() is supposed to mean "is this value all zero bits"; various parts of the code use it that way.  It shouldn't care whether the value is semantically equal to zero.  Anything doing floating-point arithmetic should be using the appropriate ConstantFP/APFloat methods.
