[PATCH, ARM, testcase] Skip target arm-neon for lp1243022.c

[Zhenqiang Chen]

Hi,

lp1243022.c will fail with options: -mfpu=neon -mfloat-abi=hard.

Logs show it does not generate auto-incremental instruction in pass
auto_inc_dec. In this case, the check of REG_INC note at subreg2 will
be invalid. So skip the check for target arm-neon.

All PASS with the following options:

-mthumb/-mcpu=cortex-a9/-mfloat-abi=hard
-mthumb/-mcpu=cortex-a9/-mfloat-abi=soft
-mthumb/-mcpu=cortex-a9/-mfloat-abi=softfp
-mthumb/-mcpu=cortex-a9/-mfloat-abi=soft/-mfpu=vfpv3
-mthumb/-mcpu=cortex-a9/-mfloat-abi=softfp/-mfpu=vfpv3
-mthumb/-mcpu=cortex-a9/-mfloat-abi=hard/-mfpu=vfpv3
-mthumb/-mcpu=cortex-a9/-mfloat-abi=soft/-mfpu=neon
-mthumb/-mcpu=cortex-a9/-mfloat-abi=softfp/-mfpu=neon
-mthumb/-mcpu=cortex-a9/-mfloat-abi=hard/-mfpu=neon
-mthumb/-mcpu=cortex-a15/-mfloat-abi=hard
-mthumb/-mcpu=cortex-a15/-mfloat-abi=soft
-mthumb/-mcpu=cortex-a15/-mfloat-abi=softfp
-mthumb/-mcpu=cortex-a15/-mfloat-abi=soft/-mfpu=vfpv4
-mthumb/-mcpu=cortex-a15/-mfloat-abi=softfp/-mfpu=vfpv4
-mthumb/-mcpu=cortex-a15/-mfloat-abi=hard/-mfpu=vfpv4
-mthumb/-mcpu=cortex-a15/-mfloat-abi=soft/-mfpu=neon
-mthumb/-mcpu=cortex-a15/-mfloat-abi=softfp/-mfpu=neon
-mthumb/-mcpu=cortex-a15/-mfloat-abi=hard/-mfpu=neon

Is it OK?

Thanks!
