Cullen Rhodes 7d4659095a [mlir][llvm] Add arm_streaming LLVM function attributes 
This patch adds two optional attributes to 'llvm.func' op for the Armv9
Streaming SVE (SSVE) mode [1] that map 1-1 with LLVM function attributes [2]:

  * arm_streaming -> aarch64_pstate_sm_enabled
  * arm_locally_streaming -> aarch64_pstate_sm_body

Streaming-mode is part of the interface (ABI) for functions with the
first attribute and it's the responsibility of the caller to manage
PSTATE.SM on entry/exit to functions with this attribute [3]. The LLVM
backend will emit 'smstart sm' / 'smstop sm' [4] around calls to
streaming functions.

In locally streaming functions PSTATE.SM is kept internal and managed by
the callee on entry/exit. The LLVM backend will emit 'smstart sm' /
'smstop sm' in the prologue / epilogue for functions with this
attribute.

The integration test for SSVE has been updated to no longer use the
passthrough mechanism that's intended for prototyping.
