This provides basic functionality for imported declarations. For
subprograms and types some amount of lazy construction is supported (so
the definition of a function can proceed the using declaration), but it
still doesn't handle declared-but-not-defined functions (since we don't
generally emit function declarations).

Variable support is really rudimentary at the moment - simply looking up
the existing definition with no support for out of order (declaration,
imported_module, then definition).

The two nested loops were confusing and also conservative in identifying
reduction variables. This patch replaces them by a worklist based approach.

A = 9
B = 3 * A - 2 * A + 1 as  B = 3 * A - (2 * A + 1)

DIBuilder::createImportedDeclaration isn't fully plumbed through (note,
lacking in AsmPrinter/DwarfDebug support) but this seemed like a
sufficiently useful division of code to make the subsequent patch(es)
easier to follow.

The idea is that docs/ReleaseNotes.rst is 3.3 and will be copied to the
branch by the release manager just before creating the release
candidates.

This ReleaseNotes_34.rst will then be moved over ReleaseNotes.rst after
the 3.3 release.

Apparently we didn't keep an association of Compile Unit metadata nodes
to DIEs so looking up that parental context failed & thus caused no
DW_TAG_imported_modules to be emitted at the CU scope. Fix this by
adding the mapping & sure up the test case to verify this.

Implement suggestions by Bill Schmidt in post-commit review. No functionality

createSystemZMCCodeGenInfo was not passing the optimization level to
InitMCCodeGenInfo(), so -O0 would be ignored.  Fixes DebugInfo/namespace.ll

We were passing an i32 to ConstantInt::get where an i64 was needed and we must
also pass the sign if we pass negatives numbers. The start index passed to
getConsecutiveVector must also be signed.

Should fix PR15882.
