This reverts commit fe5c360a9aae61db37886c0c795c409b5129905f.
The commit causes the tests below to fail on many buildbots, e.g.
https://lab.llvm.org/buildbot/#/builders/245/builds/17047
Clang :: CodeGen/aapcs-align.cpp
Clang :: CodeGen/aapcs64-align.cpp
This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

The diagnostic is unreliable, and triggers even for dead uses of
hostcall that may exist when linking the device-libs at lower
optimization levels.
Eliminate the diagnostic, and directly document the limitation for
OpenCL before code object V5.
Make some NFC changes to clarify the related code in the
MetadataStreamer.
Add a clang test to tie OCL sources containing printf to the backend IR
tests for this situation.
