…llvm#145464) This PR introduces two new ops in omp dialect, omp.target_allocmem and omp.target_freemem. omp.target_allocmem: Allocates heap memory on device. Will be lowered to omp_target_alloc call in llvm. omp.target_freemem: Deallocates heap memory on device. Will be lowered to omp+target_free call in llvm. Example: %1 = omp.target_allocmem %device : i32, i64 omp.target_freemem %device, %1 : i32, i64 The work in this PR is C-P/inspired from @ivanradanov commit from coexecute implementation: [Add fir omp target alloc and free ops](ivanradanov@be860ac) [Lower omp_target_{alloc,free} to llvm](ivanradanov@6e2d584)
