David Bolvansky 45be5e477e [UpdateTestChecks] Emit warning when invalid value for -check-prefix(es) option
Summary:
The script is silent for the following issue:
FileCheck %s -check-prefix=CHECK,POPCOUNT

FileCheck will catch it later, but I think we can warn here too.

Now it warns:
 ./update_llc_test_checks.py file.ll 
WARNING: Supplied prefix 'CHECK,POPCOUNT' is invalid. Prefix must contain only alphanumeric characters, hyphens and underscores. Did you mean --check-prefixes=CHECK,POPCOUNT?

Simon Pilgrim d82bd4d911 [utils] Fix update scripts output when run on python3.
This fixes a "bytes-like object is required, not 'str'" python3 error I hit on update_llc_test_checks.py (but present on the other scripts as well) by matching what update_mca_test_checks.py already does, plus I've added an explicit 'utf-8' encoding.

Greg Bedwell becbbe0383 [utils] Stricter checking from update_mca_test_checks.py
If any prefixes have been specified on the RUN lines that do not end up
ever actually getting printed, raise an Error. This is either an
indication that the run lines just need cleaning up, or that something
is more fundamentally wrong with the test.

Also raise an Error if there are any blocks which cannot be checked
because they are not uniquely covered by a prefix.

Fixed up a couple of tests where the extra checking flagged up issues.

Greg Bedwell 2f528f8c1e [utils] Allow better identification of matching blocks in update_mca_test_checks.py
Insert empty blocks to cause the positions of matching blocks to match
across lists where possible so that later stages of the algorithm can
actually identify them as being identical.

Regenerated all tests with this change.

Greg Bedwell a9a6d54146 [UpdateTestChecks] Error if --llvm-mca-binary gets an empty string
If the command line was mistyped like:
./update_mca_test_checks.py --llvm-mca-binary= /path/to/llvm-mca *.s
                                              ^-- extra whitespace

then /path/to/llvm-mca would get treated by argparse as a test-path
pattern and could actually be opened in write mode and overwritten.

Roman Lebedev 7b53d1454f [llvm-mca] Make sure not to end the test files with an empty line.
Summary:
It's super irritating.

[properly configured] git client then complains about that double-newline,
and you have to use `--force` to ignore the warning, since even if you
fix it manually, it will be reintroduced the very next runtime :/

Greg Bedwell e790f6fb06 [UpdateTestChecks] Improved update_mca_test_checks block analysis
Previously update_mca_test_checks worked entirely at "block" level where
a block is some sequence of lines delimited by at least one empty line.
This generally worked well, but could sometimes lead to excessive
repetition of check lines for various prefixes if some block was almost
identical between prefixes, but not quite (for example, due to a
different dispatch width in the otherwise identical summary views).

This new analyis attempts to split blocks further in the case where the
following conditions are met:
  a) There is some prefix common to every RUN line (typically 'ALL').
  b) The first line of the block is common to the output with every prefix.
  c) The block has the same number of lines for the output with every prefix.

Also, regenerated all llvm-mca test files with the following command:
update_mca_test_checks.py "../test/tools/llvm-mca/*/*.s" "../test/tools/llvm-mca/*/*/*.s"

The new analysis showed a "multiple lines not disambiguated by prefixes" warning
for test "AArch64/Exynos/scheduler-queue-usage.s" so I've also added some
explicit prefixes to each of the RUN lines in that test.

Greg Bedwell d22b35b48c [UpdateTestChecks] Fix update_mca_test_checks.py slowness issue
The script was using Python's difflib module to calculate the number of
lines changed so that it could report it in its status output.  It turns
out this can be very very slow on large sets of lines (Python bug 6931).
It's not worth the cost, so just remove the usage of difflib entirely.
