a7b19157ba [OPENMP] Fix PR34927: Emit initializer for reduction array with declare
reduction.

If the reduction is an array or an array section and reduction operation
is declare reduction without initializer, it may lead to crash.

93786da2cb Make '-disable-llvm-optzns' an alias for '-disable-llvm-passes'.
Much to my surprise, '-disable-llvm-optzns' which I thought was the
magical flag I wanted to get at the raw LLVM IR coming out of Clang
deosn't do that. It still runs some passes over the IR. I don't want
that, I really want the *raw* IR coming out of Clang and I strongly
suspect everyone else using it is in the same camp.

There is actually a flag that does what I want that I didn't know about
called '-disable-llvm-passes'. I suspect many others don't know about it
either. It both does what I want and is much simpler.

This removes the confusing version and makes that spelling of the flag
an alias for '-disable-llvm-passes'. I've also moved everything in Clang
to use the 'passes' spelling as it seems both more accurate (*all* LLVM
passes are disabled, not just optimizations) and much easier to remember
and spell correctly.

This is part of simplifying how Clang drives LLVM to make it cleaner to
wire up to the new pass manager.

8fbae8cf09 [OPENMP] Fix crash on initialization of classes with no init clause in
declare reductions.

If reduction clause is applied to instance of class with user-defined
reduction operation without initialization clause, it may cause a crash.
Patch fixes this issue.

a839dddf92 [OPENMP 4.0] Use 'declare reduction' constructs in 'reduction' clauses.
OpenMP 4.0 allows to define custom reduction operations using '#pragma
omp declare reduction' construct. Patch allows to use this custom
defined reduction operations in 'reduction' clauses.
