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
38001110: ea4f 0890 mov.w r8, r0, lsr #2
38001114: ea4f 09d1 mov.w r9, r1, lsr #3
38001118: ea4f 0a92 mov.w sl, r2, lsr #2
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. **

It takes about 10 cycles to obtain the task list according to the task
status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.
