This makes adding projects to LLVM_ENABLE_PROJECTS possible.

Summary:
When specifying symbolic permissions with + or -, if none of
a/u/g/o are specified, bits set in the umask are not affected.
This caused the llvm-lipo executability tests to fail on some
systems, e.g. having an umask of 027 would cause chmod -x to not
clear the executable bit for others. This change instead
uses chmod a-x, which clears all the executable bits regardless
of umask.

Summary:
This allows reporting undefined symbols before LTO codegen is
run. Since LTO codegen can take a long time, this improves user
experience by avoiding that time spend if the link is going to
fail with undefined symbols anyway.

Fixes PR32400.

Adds machine operand lowering for MCSymbolSDNodes to the PowerPC
backend. This is needed to produce call instructions in assembly for AIX
because the callee operand is a MCSymbolSDNode. The test is XFAIL'ed for
asserts due to a (valid) assertion in PEI that the AIX ABI isn't supported yet.

Set environment variables to empty values rather than attempting
to unset them via 'env -u', in order to fix NetBSD test regression
caused by r366980.  POSIX does not guarantee that env(1) supports '-u'

Enable dumping output only if FILECHECK_DUMP_INPUT_ON_FAILURE is set to

Summary:
These aren't formally subexpressions in C++, in this case + is left-associative.
However informally +, *, etc are usually (mathematically) associative and users
consider these subexpressions.

We detect these and in simple cases support extracting the partial expression.
As well as builtin associative operators, we assume that overloads of them
are associative and support those too.

Summary:
Reduction variables are the variables, for which the private copies
must be created in the OpenMP regions. Then they are initialized with
the predefined values depending on the reduction operation. After exit
from the OpenMP region the original variable is updated using the
reduction value and the value of the original reduction variable.
