Registers S0-S15 (D0-D7, Q0-Q3) do not need to be preserved. They can be used for passing
arguments or returning results in standard procedure-call variants.
Registers D16-D31 (Q8-Q15), do not need to be preserved.

l3/l4 stack will decouple the reference of d_buf gradually, Only legacy
devices still retain d_buf support, new net devices will use d_iob

Fix build break on thumb2 mode:
opus/celt/arm/celt_pitch_xcorr_arm-gnu.S: Assembler messages:
opus/celt/arm/celt_pitch_xcorr_arm-gnu.S:146: Error: thumb conditional instruction should be in IT block -- `movle pc,lr'
Reference:
https://developer.arm.com/documentation/100067/0612/armclang-Command-line-Options/-mimplicit-it
In A32 code, the integrated assembler accepts all conditional instructions
without giving an error or warning. In T32 code, the integrated assembler
outputs an implicit IT block when there is a conditional instruction
without an enclosing IT block. The integrated assembler does not give an
error or warning about this.

The option '-mthumb' is only valid for C source files and it is not passed to the assembler.
If 'thumb' is not considered in some assembly projects, the system will generate
'undefined instructions' when running incompatible instruction:
arm_undefinedinsn: Undefined instruction at 0x380cfc98
This assembly file should be compiled with .thumb but it doesn't:
380cfc90 <hobot_i8_i32_gemm_nn_m4_n8_neon>:
380cfc90: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr}
380cfc94: ed2d8b10 vpush {d8-d15}
380cfc98: e59d4064 ldr r4, [sp, #100] ; 0x64 <-- Undefined instruction
380cfc9c: e59d5068 ldr r5, [sp, #104] ; 0x68
380cfca0: e59d606c ldr r6, [sp, #108] ; 0x6c
380cfca4: e59d7070 ldr r7, [sp, #112] ; 0x70
380cfca8: e1a08120 lsr r8, r0, #2
380cfcac: e1a091a1 lsr r9, r1, #3
380cfcb0: e1a0a122 lsr sl, r2, #2
After enable thumb:
.syntax unified
.thumb
or
-Wa,-mthumb
.Lhobot_i8_i32_gemm_nn_m4_n8_neon:
38001100: e92d 4ff0 stmdb sp!, {r4, r5, r6, r7, r8, r9, sl, fp, lr}
38001104: ed2d 8b10 vpush {d8-d15}
38001108: 9c19 ldr r4, [sp, #100] ; 0x64
3800110a: 9d1a ldr r5, [sp, #104] ; 0x68
3800110c: 9e1b ldr r6, [sp, #108] ; 0x6c
3800110e: 9f1c ldr r7, [sp, #112] ; 0x70

This commit will enable the thumb option of the assembly file by default,
so that when compiling the assembly file, the machine code and the system will be in a consistent state.
----------------------------------------------------------------

GCC Manual:
-mthumb
Generate code for the Thumb instruction set. The default is to use the 32-bit ARM
instruction set. This option automatically enables either 16-bit Thumb-1 or mixed 16/32-bit
Thumb-2 instructions based on the -mcpu=name and -march=name options.
** This option is not passed to the assembler. **
** If you want to force assembler files to be interpreted as Thumb code,
either add a `.thumb' directive to the source or pass the -mthumb option
directly to the assembler by prefixing it with -Wa. **
