Simon Pilgrim ee7694442d [Utils][X86] Help update_llc_test_checks.py to recognise retl/retq to reduce CHECK duplication (PR35003) 
This patch replaces the --x86_extra_scrub command line argument to automatically support a second level of regex-scrubbing if it improves the matching of nearly-identical code patterns. The argument '--extra_scrub' is there now to force extra matching if required.

This is mostly useful to help us share 32-bit/64-bit x86 vector tests which only differs by retl/retq instructions, but any scrubber can now technically support this, meaning test checks don't have to be needlessly obfuscated.

I've updated some of the existing checks that had been manually run with --x86_extra_scrub, to demonstrate the extra "ret{{[l|q]}}" scrub now only happens when useful, and re-run the sse42-intrinsics file to show extra matches - most sse/avx intrinsics files should be able to now share 32/64 checks.

Tested with the opt/analysis scripts as well which share common code - AFAICT the other update scripts use their own versions.

Simon Pilgrim 5334a2c571 [UpdateTestChecks] Add update_analyze_test_checks.py for cost model analysis generation 
The script allows the auto-generation of checks for cost model tests to speed up their creation and help improve coverage, which will help a lot with PR36550.

If the need arises we can add support for other analyze passes as well, but the cost models was the one I needed to get done - at the moment it just warns that any other analysis mode is unsupported.

I've regenerated a couple of x86 test files to show the effect.

Alexander Richardson 115b0673b6 [UpdateTestChecks] Handle IR variables with a '-' in the name 
Summary:
I noticed that clang will emit variables such as %indirect-arg-temp when
running update_cc1_test_checks.py and therefore update_cc1_test_checks.py
wasn't adding FileCheck captures for those variables.

Fangrui Song 0a301a194e [utils] Add utils/update_cc_test_checks.py 
A utility to update LLVM IR in C/C++ FileCheck test files.

Example RUN lines in .c/.cc test files:

// RUN: %clang -S -Os -DXX %s -o - | FileCheck %s
// RUN: %clangxx -S -Os %s -o - | FileCheck -check-prefix=IR %s

Usage:

% utils/update_cc_test_checks.py --llvm-bin=release/bin test/a.cc
% utils/update_cc_test_checks.py --c-index-test=release/bin/c-index-test --clang=release/bin/clang /tmp/c/a.cc

    // NOTE: Assertions have been autogenerated by utils/update_cc_test_checks.py
    // RUN: %clang -emit-llvm -S -Os -DXX %s -o - | FileCheck -check-prefix=AA %s
    // RUN: %clangxx -emit-llvm -S -Os %s -o - | FileCheck -check-prefix=BB %s
    using T =
    #ifdef XX
        int __attribute__((vector_size(16)))
    #else
        short __attribute__((vector_size(16)))
    #endif
        ;

    // AA-LABEL: _Z3fooDv4_i:
    // AA:       entry:
    // AA-NEXT:    %add = shl <4 x i32> %a, <i32 1, i32 1, i32 1, i32 1>
    // AA-NEXT:    ret <4 x i32> %add
    //
    // BB-LABEL: _Z3fooDv8_s:
    // BB:       entry:
    // BB-NEXT:    %add = shl <8 x i16> %a, <i16 1, i16 1, i16 1, i16 1, i16 1, i16 1, i16 1, i16 1>
    // BB-NEXT:    ret <8 x i16> %add
    T foo(T a) {
      return a + a;
    }

Justin Bogner 35a9d1b17f update_mir_test_checks: Use the regexes from UpdateTestChecks.common 
Some of the update_*_test_checks regexes have been moved into a
library, so we might as well use them in update_mir_test_checks.
Also includes minor bugfixes to the regexes that are there so we
don't regress update_mir_test_checks
