  Log Message:
  -----------
  [Clang][SVE] NFC: Move info about ACLE types into separate function.

This function returns a struct `BuiltinVectorTypeInfo` that contains
the builtin vector's element type, element count and number of vectors
(used for vector tuples).

  Log Message:
  -----------
  [AArch64][SVE] Fix calculation restore point for SVE callee saves.

This fixes an issue where the restore point of callee-saves in the
function epilogues was incorrectly calculated when the basic block
consisted of only a RET instruction. This caused dealloc instructions
to be inserted in between the block of callee-save restore instructions,
rather than before it.

  Log Message:
  -----------
  [AArch64][SVE] Add missing debug info for ACLE types.

This patch adds type information for SVE ACLE vector types,
by describing them as vectors, with a lower bound of 0, and
an upper bound described by a DWARF expression using the
AArch64 Vector Granule register (VG), which contains the
runtime multiple of 64bit granules in an SVE vector.
