[LowerTypeTests][NewPM] Add constructor that uses command line flags

This matches the legacy PM pass by having one constructor use command
line flags, and the other use parameters to the pass.

This fixes all tests under Transforms/LowerTypeTests using NPM.

[AArch64][GlobalISel] If a G_BUILD_VECTOR operands are all G_CONSTANT then assign to gpr bank.

Even if the type is s8/s16, assigning to gpr is preferable with constants because
worst case we can select via a constant pool load, and without cross-bank copies
to the FPR bank more patterns can be imported later.

[Clang][OpenMP] Added support for nowait target in CodeGen via regular task

Previously for nowait target, CG emitted a function call to `__tgt_target_nowait`, etc. However, in OpenMP RTL, these functions just directly call the no-nowait version, which means nowait is not working as expected.

OpenMP specification says a target is acutally a target task, which is an untied and detachable task. It is natural to go to the direction that generates a task for a nowait target. However, OpenMP task has a problem that it must be within to a parallel region; otherwise the task will be executed immediately. As a result, if we directly wrap to a regular task, the `target nowait` outside of a parallel region is still a synchronous version.

In D77609, I added the support for unshackled task in OpenMP RTL. Basically, unshackled task is a task that is not bound to any parallel region. So all nowait target will be tranformed into an unshackled task. In order to distinguish from regular task, a new flag bit is set for unshackled task. This flag will be used by RTL for later process.

Since all target tasks are allocated via `__kmpc_omp_target_task_alloc`, and in current `libomptarget`, `__kmpc_omp_target_task_alloc` just calls `__kmpc_omp_task_alloc`. Therefore, we can modify the flag in `__kmpc_omp_target_task_alloc` so that we don't need to modify the FE too much. If users choose to opt out the feature, they just need to use a RTL w/o support of unshackled threads.

As a result, in this patch, the `target nowait` region is simply wrapped into a regular task. Later once we have RTL support for unshackled tasks, the wrapped tasks can be executed by unshackled threads w/o changes in the FE.
