Another step towards getting rid of dependencies to the legacy
pass manager.
Primary change here is to just do -passes=foo instead of -foo in
simple situations (when running a single transform pass). But also
updated a few test running multiple passes.
Also removed some "duplicated" RUN lines in a few tests that where
using both -foo and -passes=foo syntax. No need to do the same kind
of testing twice.
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

These are uncontroversial and independent of a proposed LangRef edits (D44216).
I tried to fix tests that would fold away:
rL327004
rL327028
rL327030
rL327034
I'm not sure if the Reassociate tests are meaningless yet, but they probably will be
as we add more folds, so if anyone has suggestions or wants to fix those, please do.

The reassociate pass generates named values such as "%tmp2" which trips up the script's regex's
because the script uses a 'TMP' prefix for unnamed values (%2).

Before reevaluating instructions, iterate over all instructions
to be reevaluated and remove trivially dead instructions and if
any of it's operands become trivially dead, mark it for deletion
until all trivially dead instructions have been removed
