Since the vector.print str provides no punctuation control, it is
slightly more flexible to let the client of this operation decide
whether there should be a trailing newline. This allows for printing
like
vector.print str "nse = "
vector.print %nse : index
as
nse = 42
This adds a new `mlir_arm_runner_utils` library that contains utils
specific to Arm/AArch64. This is for use in MLIR integration tests.
This initial patch adds `setArmVLBits()` and `setArmSVLBits()`. This
allows changing vector length or streaming vector length at runtime (or
setting it to a known minimum, i.e. 128-bits).
