[PATCH v1 1/1] aarch64: Mark `vreinterpret` intrinsics streaming-compatible

[Karl Meakin via Sourceware Forge]

From: Karl Meakin <karl.mea...@arm.com>

The ACLE says that `vreinterpret` intrinsics are not streaming-compatible, but
they are all no-ops at runtime so should be streaming-compatible in practice.

gcc/ChangeLog:

        * config/aarch64/aarch64-neon-builtins-base.def (vreinterpret,
        vreinterpretq): Change `REQUIRED_EXTENSIONS` to
        `streaming_compatible (AARCH64_FL_SIMD)`.
