[OpenMP][NFC] Reuse OMPIRBuilder `struct ident_t` handling in Clang Replace the `ident_t` handling in Clang with the methods offered by the OMPIRBuilder. This cuts down on the clang code as well as the differences between the two, making further transitions easier. Tests have changed but there should not be a real functional change. The most interesting difference is probably that we stop generating local ident_t allocations for now and just use globals. Given that this happens only with debug info, the location part of the `ident_t` is probably bigger than the test anyway. As the location part is already a global, we can avoid the allocation, memcpy, and store in favor of a constant global that is slightly bigger. This can be revisited if there are complications.

[CodeGen] Emit a call instruction instead of an invoke if the called llvm function is marked nounwind This fixes cases where an invoke is emitted, despite the called llvm function being marked nounwind, because ConstructAttributeList failed to add the attribute to the attribute list. llvm optimization passes turn invokes into calls and optimize away the exception handling code, but it's better to avoid emitting the code in the front-end if the called function is known not to raise an exception.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

[OpenMP][NFC] Reuse OMPIRBuilder `struct ident_t` handling in Clang Replace the `ident_t` handling in Clang with the methods offered by the OMPIRBuilder. This cuts down on the clang code as well as the differences between the two, making further transitions easier. Tests have changed but there should not be a real functional change. The most interesting difference is probably that we stop generating local ident_t allocations for now and just use globals. Given that this happens only with debug info, the location part of the `ident_t` is probably bigger than the test anyway.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

[OpenMP][NFC] Reuse OMPIRBuilder `struct ident_t` handling in Clang Replace the `ident_t` handling in Clang with the methods offered by the OMPIRBuilder. This cuts down on the clang code as well as the differences between the two, making further transitions easier. Tests have changed but there should not be a real functional change. The most interesting difference is probably that we stop generating local ident_t allocations for now and just use globals. Given that this happens only with debug info, the location part of the `ident_t` is probably bigger than the test anyway. As the location part is already a global, we can avoid the allocation, memcpy, and store in favor of a constant global that is slightly bigger. This can be revisited if there are complications.

NFC: update clang tests to check ordering and alignment for atomicrmw/cmpxchg. The ability to specify alignment was recently added, and it's an important property which we should ensure is set as expected by Clang. (Especially before making further changes to Clang's code in this area.) But, because it's on the end of the lines, the existing tests all ignore it. Therefore, update all the tests to also verify the expected alignment for atomicrmw and cmpxchg. While I was in there, I also updated uses of 'load atomic' and 'store atomic', and added the memory ordering, where that was missing.

This cuts down on the clang code as well as the differences between the two, making further transitions easier. Tests have changed but there should not be a real functional change. The most interesting difference is probably that we stop generating local ident_t allocations for now and just use globals. Given that this happens only with debug info, the location part of the `ident_t` is probably bigger than the test anyway. As the location part is already a global, we can avoid the allocation, memcpy, and store in favor of a constant global that is slightly bigger. This can be revisited if there are complications.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.
