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.
Debugify in OriginalDebugInfo mode, introduced with D82545,
runs only with legacy PassManager.
This patch enables this utility for the NewPM.

Debugify in OriginalDebugInfo mode, does (DebugInfo) collect-before-pass & check-after-pass
for each instruction, which is pretty expensive. When used to analyze DebugInfo losses
in large projects (like LLVM), this raises the build time unacceptably.
This patch introduces a limit for the number of processed functions per compile unit.
By default, the limit is set to UINT_MAX (practically unlimited), and by using the introduced
option -debugify-func-limit the limit could be set to any positive integer number.

Before this patch the DebugifyLevel option was used for
the synthetic mode, so after this, it will be used in
the original mode as well.

Summary:
It can be helpful to test behaviour w.r.t locations without having DEBUG_VALUE
around. In particular, because DEBUG_VALUE has the potential to change CodeGen
behaviour (e.g. hasOneUse() vs hasOneNonDbgUse()) while locations generally
don't.
