7a6f5c77c4 [AArch64]Fix the problems that can't select mul/add/sub of v1i8/v1i16/v1i32 types. 
As this problems are similar to shl/sra/srl, also add patterns for shift nodes.

b9536ac581 [AArch64 NEON] Expand vector for UDIV/SDIV/UREM/SREM/FREM as neon doesn't support these operations.

3796015b5b [AArch64]Fix the problem that can't select mul of v1i64/v2i64 types. 
E.g. Can't select such IR:
     %tmp = mul <2 x i64> %a, %b

24802f3f82 Fix Incorrect CHECK message [0-31]+ in test case. 
In regular expression, [0-31]+ equals to [0-3]+, not the number from
0 to 31. So change it to [0-9]+.

87773c318f AArch64: add initial NEON support 
Patch by Ana Pazos.

- Completed implementation of instruction formats:
AdvSIMD three same
AdvSIMD modified immediate
AdvSIMD scalar pairwise

- Completed implementation of instruction classes
(some of the instructions in these classes
belong to yet unfinished instruction formats):
Vector Arithmetic
Vector Immediate
Vector Pairwise Arithmetic

- Initial implementation of instruction formats:
AdvSIMD scalar two-reg misc
AdvSIMD scalar three same

- Intial implementation of instruction class:
Scalar Arithmetic

- Initial clang changes to support arm v8 intrinsics.
Note: no clang changes for scalar intrinsics function name mangling yet.

- Comprehensive test cases for added instructions
To verify auto codegen, encoding, decoding, diagnosis, intrinsics.
