This will add eBPF JIT support to the 32-bit ARCv2 processors. The
implementation is qualified by running the BPF tests on a Synopsys HSDK
board with "ARC HS38 v2.1c at 500 MHz" as the 4-core CPU.

I see noticeable improvements on every selected test. To list a few:

Hello list,
I know this is not a small patch, but could someone skim over it?
If there's anything that I can do to make the review process easier,

I have tried [1] this and the test execution time took a performance hit of
35%. Therefore, I have not included
