  Hexagon HVX (tests/tcg/hexagon) histogram test (2021-11-03 16:01:38 -0500)

----------------------------------------------------------------
This series adds support for the Hexagon Vector eXtensions (HVX)

These instructions are documented here
https://developer.qualcomm.com/downloads/qualcomm-hexagon-v66-hvx-programmer-s-reference-manual

Hexagon HVX is a wide vector engine with 128 byte vectors.

See patch 01 Hexagon HVX README for more information.

*** Changes in v2 ***
Remove HVX tests from makefile to avoid need for toolchain upgrade
