IR printing for single function with the new pass manager.
Summary:
The IR printing always prints out all functions in a module with the new pass manager, even with -filter-print-funcs specified. This is being fixed in this change. However, there are two exceptions, i.e, with user-specified wildcast switch -filter-print-funcs=* or -print-module-scope, under which IR of all functions should be printed.
Test Plan:
make check-clang
make check-llvm
