Extended Description

I have a module which seems to be working fine, it verifies, compiles with llc etc. However a specific optimization route turns the IR invalid on the simplifycfg pass.

Steps to reproduce:

opt -o=foo.bc -simplifycfg SharedLib.bc

[llvmbot]

somewhat reduced testcase (.ll)

[llvmbot]

fairly minimal testcase

Fixed.
