to use the -passes syntax when specifying the pipeline.

Given that LLVM_ENABLE_NEW_PASS_MANAGER isn't set to off (which is
a deprecated feature) the updated test cases already used the new
pass manager, but they were using the legacy syntax when specifying
the passes to run. This patch can be seen as a step toward deprecating
that interface.

This patch also removes some redundant RUN lines. Here I am
referring to test cases that had multiple RUN lines verifying both
the legacy "-passname" syntax and the new "-passes=passname" syntax.
Since we switched the default pass manager to "new PM" both RUN lines
have verified the new PM version of the pass (more or less wasting
time running the same test twice), unless LLVM_ENABLE_NEW_PASS_MANAGER
is set to "off". It is assumed that it is enough to run these tests
with the new pass manager now.
