9b4aa600e5 Fix ptr overflow warning in filter_ar.c
In this code, the problem was that the ptr could sometimes point
outside of the allocated arrays, in particular before the array,
causing a pointer overflow warning. However, the memory pointed to was
never read or written while the pointer was off.

With this change, we keep an index instead of a pointer, which avoids
warnings for pointer overflow. The index might be negative at times,
but the index will not be used to address the arrays while negative.

7aabd39b4b Move asm_defines.h to rtc_base/system/
This moves it from an API directory (system_wrappers/include/) to a
non-API directory, which is exactly what we want for utilities like
this.

ee67ca3fd8 Replace left shift with equivalent multiplication.
We have done changes to the Audio Processing fuzzer here
https://webrtc-review.googlesource.com/c/src/+/36500/6.

We ran the new version of the fuzzer locally. The UBSAN
detector found these (minor) issues.

We have used the Godbolt compiler explorer to check that similar
changes produce identical compiled code.

6f54e7ab67 Avoid integer-overflow in WebRtcSpl_FilterARFastQ12
Simply use int64_t instead of int32_t for two local variables.
This avoids integer-overflow in some rare cases.

ComfortNoiseDecoder.

The change also includes a fix to an issue in WebRtcSpl_FilterAR, which
was immediately found by running the fuzzer locally.

e40468ba3d Move some numeric utility code from rtc_base/ to rtc_base/numerics/
Specifically, I'm moving

  safe_compare.h
  safe_conversions.h
  safe_minmax.h

They shouldn't be part of the API, and moving them to an appropriate
subdirectory of rtc_base/ is a good way to keep track of that.

7120742701 Adding NOLINT for typedefs.h and common_types.h
Now that we have moved WebRTC from src/webrtc to src/, common_types.h
and typedefs.h are triggering a cpplint error.

The cpplint complaint is:
Include the directory when naming .h files  [build/include] [4]

This CL disables the error but we have to remove these two headers
from the root directory.
