  Log Message:
  -----------
  [AArch64][GlobalISel] Adopt some Ld* patterns to reduce codegen regressions (#135492)

This is an update of #69607 after #101675 and #105686.

Ld1Lane64Pat, Ld1Lane128Pat, LoadInsertPatterns, Neon_INS_elt_pattern
from SelectionDAG didn't work for GlobalISel on v8i8 and v16i8 vector
types, because vector_insert for v8i8, v16i8 in SelectionDAG expects i32
scalar argument type, whereas G_INSERT_VECTOR_ELT expects s8.
