[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC) 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. Differential Revision: https://reviews.llvm.org/D123115

[OpenCL][PR41727] Prevent ICE on global dtors Pass NULL to pointer arg of __cxa_atexit if addr space is not matching with its param. This doesn't align yet with how dtors are generated that should be changed too. Differential Revision: https://reviews.llvm.org/D62413 llvm-svn: 366059

Create SPIRABIInfo to enable SPIR_FUNC calling convention. Background: Call to library arithmetic functions for div is emitted by the compiler and it set wrong “C” calling convention for calls to these functions, whereas library functions are declared with `spir_function` calling convention. InstCombine optimization replaces such calls with “unreachable” instruction. It looks like clang lacks SPIRABIInfo class which should specify default calling conventions for “system” function calls. SPIR supports only SPIR_FUNC and SPIR_KERNEL calling convention. Reviewers: Erich Keane, Anastasia Differential Revision: https://reviews.llvm.org/D92721
