Sanjay Patel 7bee94410c [InstCombine] form copysign from select of FP constants (PR44153) 
This should be the last step needed to solve the problem in the
description of PR44153:
https://bugs.llvm.org/show_bug.cgi?id=44153

If we're casting an FP value to int, testing its signbit, and then
choosing between a value and its negated value, that's a
complicated way of saying "copysign":

(bitcast X) <  0 ? -TC :  TC --> copysign(TC,  X)
