Fix gem5 userland fatal: kernel too old.

Fix https://github.com/cirosantilli/linux-kernel-module-cheat/issues/64
gem5 x86 boot fails with: "Assertion `locked && curr_frag_id == 0' failed

So we are now back to mainline gem5!

fedb68c62c merge test-user-mode and test-baremetal into test-executables 
Differentiate with --mode userland vs --mode baremetal.

The code was basically copied, now it's DRY.

6994dc21af test-gdb: can now run in either userland or baremetal modes 
Selection with --mode userland (default because has x86_64) or --mode baremetal.

This is the first userland tool where this choice is done on the command line,
which led to a refactor of supported_archs and is_baremetal and is_userland
into a single self.env['mode'].

c8c4f89854 asm: make use regular asserts that will just work on baremetal 
Previously had wonky line pointer in asm_main. New interface simpler and more portable.

Add tests for ASSERT_EQ_ and family in arm and aarch64, previously on x86_64.

ASSERT_EQ_ and family in ARM can now either take =123, =addr or var, before this
the = was added on macros so var was not possible.

Define the main function directly in assembly, the C driver was useless.

01984c2201 test-boot: run in parallel 
--quit-after-boot: fix for gem5, update path to gem5.sh

Improve the printing of results and errors:

- remove newlines from IDs at the end for ./test-boot
- remove newlines from progress for __call__ commands and don't print executed commands at all,
  otherwise there are too many lines per test and it is hard to tell what is going on
- print backtraces for any exception in the threads (bugs while developing this code)

Tests across different archs and emulators are still not running in parallel,
which is a huge loss. TODO.

thread_pool: introduce with API. This was motivate by test-boot, I've had enough
of doing separate error handling for each loop type! Greatly dries up the code, awesome.

common: make --all-emulators work properly with native hopefully for the last time,
./test-baremetal was still failing.

gem5: don't pass --command-line for baremetal. Maybe later we can use it to actually
pass command line arguments to main()? To be seen.

5391bc1bfd Get rid of lkmc_assert_fail in favor of abort + assert

I had done that previously and forgotten to do this conversion!
