I think something broke with this patch.
If I run
```
valgrind llc -mtriple=x86_64-pc-linux-gnu -enable-new-pm -print-pipeline-passes -filetype=null test/tools/llc/new-pm/pipeline.ll
```
with this patch I get a
```
==3681339== Conditional jump or move depends on uninitialised value(s)
```
complaint, and on some downstream buildbots I see a libc error
```
14:54:29 *** Error in `/repo/.../bin/llc': free(): invalid pointer: 0x00007fa3183497d8 ***
```
when running the same testcase.
