clang/AMDGPU: Pass BoundArch through device libs handling
Pre-work to consolidate target identification for future target
option bug fixes. Also requires updating flang to match recent
clang changes.

clang: Add BoundArch argument to addClangTargetOptions (#196504)
addClangTargetOptions already has an OffloadKind argument,
but it kind of doesn't make sense for any function to know the
OffloadKind, but not the associated BoundArch.
The current process is kind of convoluted. TranslateArgs
synthesizes a -mcpu argument from BoundArch, and later
addClangTargetOptions re-parses that -mcpu argument each
time it wants the architecture. Add this argument so this
can be cleaned up in a future change.

[mlir][acc] Add acc.predicate_region for redundant/single semantics (#203011)
Add acc.predicate_region, an intermediate codegen operation that groups
statements at intermediate points in a loop nest within
acc.compute_region. OpenACC distinguishes partitioned loop execution
from single and redundant execution at nest transitions: for example,
gang-redundant code runs on all gangs but not as partitioned gang-loop
iterations, and worker-single or vector-single code runs on one worker
or vector lane rather than across the full worker or vector partition.
This grouping marks code whose execution scope differs from surrounding
partitioned loops, so predication and synchronization can be applied
correctly during lowering.
[flang][semantic] parser node types and rewrite for explicit-shape-bounds-spec (#188447)
This commit lays the groundwork for semantic analysis of rank-1 integer array expressions being used as bounds in a declaration with explicit bounds.
