bugpoint result

Clang 7 as well as Clang 8 ran into errors while compiling the respective
compiler-rt.

Tracing the bug led me to a crashing llc:


    > llc -asm-show-inst -asm-verbose bugpoint-reduced-simplified.bc
    LLVM ERROR: Cannot select: 0x55d58830cbf0: f80 =
ConstantFP<APFloat(604462909807314587353088)>
    In function: __mulxc3

The .bc file is attached.
