Update the FuncToLLVM pass to use the generated constructors and the generated pass option struct. The hand written constructor got out of sync after some refactorings. Using a generated constructor and options struct ensures the everything remains in sync. Reviewed By: zero9178 This reverts commit 39da46826da82c24ca4407c13ad7feb8e5dc32a1 and relands commit 771d9c05afc2515b474fb53db857716dfdfc1dcf which was originally reverted due to https://lab.llvm.org/buildbot#builders/61/builds/39694 Differential Revision: https://reviews.llvm.org/D143733
