[PATCH] D95380: Turn on the new pass manager by default

In the context of https://bugs.llvm.org/show_bug.cgi?id=49606, I realized that most developers are probably still using the old pass manager. That issue only repros with the new PM, and @jdoerfert was using the legacy PM. I checked my local build dir, and observed this line in it:

  ENABLE_EXPERIMENTAL_NEW_PASS_MANAGER:BOOL=FALSE

One way to deal with this would be to deprecate the legacy spelling of `ENABLE_EXPERIMENTAL_NEW_PASS_MANAGER` and switch to `LLVM_ENABLE_NEW_PASS_MANAGER`. If we don't do this, we'll have to make a PSA about clearing CMakeCache.txt anyway, so I think it's probably worth it.
