We can already update multiple files in each update call, this extends it to work with wildcards as well in the same way as update_mca_test_checks.py (to support shells that won't do this for us - windows command prompt etc.)

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.

Make sure all print statements are compatible with Python 2 and Python3 using
the `from __future__ import print_function` statement.

Summary:
This revision refactors 1. parser 2. CHECK line adder of utils/update_{,llc_}test_checks.py
so that thir functionality can be re-used by other utility scripts (e.g. D42712)

The dream of a unified check-line auto-generator for all phases of compilation is dead.
The llc script has already diverged to be better at its goal, so having 2 scripts that
do almost the same thing just causes confusion. Now, this script will only work with
opt to produce check lines for IR transforms.

Correct handling of the following FileCheck options is implemented in
update_llc_test_checks.py and update_test_checks.py scripts:
1) -check-prefix (with a single dash)
2) -check-prefixes (with multiple prefixes)

Summary:
Prior to this change, phi nodes were never considered defs, and so we ended up with undefined variables for any loop. Now, instead of trying to find just defs, we iterate over each actual IR value in the line, and replace them one by one with either a definition or a use.
We also don't try to match anything in the comment portions of the line.
I've tested it even on things like function pointer calls, etc, and against existing test cases uses update_test_checks
With this change, we are able to use update_tests on the cyclic cases in newgvn.
The only case i'm aware of that will misfire is if you have a string with which contains a valid token.
However, this is the same as it is now, with a slightly larger set of strings that may misfire.
Prior to this change, a test with the string " %a =" would be replaced.

This patch adds support for including the avx512 mask register information in the mask/maskz versions of shuffle instruction comments.
This initial version just adds support for MOVDDUP/MOVSHDUP/MOVSLDUP to reduce the mass of test regenerations, other shuffle instructions can be added in due course.

The script now replace '.LCPI888_8' style asm symbols with the {{\.LCPI.*}} re pattern - this helps stop hardcoded symbols in 32-bit x86 tests changing with every edit of the file
Refreshed some tests to demonstrate the new check
llvm-svn: 272488
We could make this an option if people don't like it.
But since part of the reason for using a script to generate
checks is to prevent lazy checking that lets bugs crawl
through, let's have the script check the first line too.
For asm tests, it ensures that nothing unexpected has
happened before the first line of asm. This matches the
existing behavior of update_llc_test_checks.py.

This is an enhancement of the existing update_llc_test_checks.py script.
It adds some of the functionality from the script used in D17999 to make
the IR checking more flexible.
The bad news:
This actually is 'My First Python Program'. Thus, it's likely that I have
violated all best practices of Python programming if I've made a functional
change from the original program. If you see anything that's obviously
wrong, please let me know or feel free to fix it. I didn't even read any
documentation...
The good news:
I tested this on ~10 existing opt/llc regression tests, and it does what
I hoped for. It produces exact checking for IR regression tests and doesn't
signficantly change the existing llc-with-x86-target asm checking. The opt
tests that were modified in r263667, r263668, r263674, and r263679 are
examples of the expected results, except that this version of the script
puts the check lines ahead of the IR to follow the existing llc/asm
behavior.
If there are no complaints/fallout, we should be able to remove the
original script. Extending this script to be used for non-x86 and clang
regression tests would be the expected follow-up steps.
