[UpdateLLCTestChecks] Add support for isel debug output in update_llc_test_checks.py

Add a check on run lines to pick up isel options in llc commands and allow
generating check lines of isel final output other than assembly. If llc command
line contains -debug-only=isel, update_llc_test_checks.py will try to scrub isel
output, otherwise, the script will fall back on default behaviour, which is try to
scrub assembly output instead.

The motivation of this change is to allow usage of update_llc_test_checks.py to
autogenerate checks of instruction selection results. In this way, we can detect
errors at an earlier stage before the compilation goes all the way to assembly.
It is an example of having some transparency for the stages between IR and
assembly. These generated tests are almost like "unit tests" of isel stage.

This patch only implements the initial change to differentiate isel output from
assembly output for Lanai. Other targets will not be supported for isel check
generation at the moment. Although adding support for it will only require
implementing the function regex and scrubber for corresponding targets.

The Lanai implementation was chosen mainly for the simplicity of demonstrating
the difference between isel checks and asm checks.

This patch also do not include the implementation of function prefix, which is
required for the generated isel checks to pass. I will put up a follow up revision
for the function prefix change to complete isel support.

[UpdateTestChecks] Re-add --filter and --filter-out options

Re-add filtering options with fixes for failed tests. We were not passing the
is_filtered argument in all check generator calls in update_cc_test_checks.py

Enhance the various update_*_test_checks.py tools to allow filtering the tool
output with regular expressions. The --filter option will emit only tool output
lines matching the given regular expression while the --filter-out option will
emit only tools output lines not matching the given regular expression. Filters
are applied in order of appearance on the command line (or in UTC_ARGS) and the
first matching filter terminates the search.

This allows test authors to create more focused tests by removing irrelevant
tool output and checking only the pieces of output necessary to test the desired
functionality.

[M68k][test](6/8) Add all of the tests

And a small utilities -- extract-section.py -- that helps extracting
specific object file section and printing in textual format. This
utility is just a workaround for tests inside `Encoding`. Hopefully in
the future we can replace dependencies in those tests with existing tools
(e.g. llvm-readobj). Please refer to this bug for more context:
https://bugs.llvm.org/show_bug.cgi?id=49245

Note that since we don't have AsmParser for now, we are testing the MC
part using MIR as input and put those tests under the `Encoding` folder.
In the future when AsmParser (and disassembler) is finished, those tests
will be moved to `test/MC/M68k`.
