[NewPM][PassInstrumentation] IR printing support from clang driver 

Summary: https://reviews.llvm.org/D50923 enabled the IR printing support for the new pass manager, but only for the case when `opt` tool is used as a driver. This patch is to enable the IR printing when `clang` is used as a driver.
