Improvements

• Running tests in random order (--order rand) has been reworked significantly (#1908)
  • Given same seed, all platforms now produce the same order
  • Given same seed, the relative order of tests does not change if you select only a subset of them
• Vector matchers support custom allocators (#1909)
• | and & (bitwise or and bitwise and) are now supported in CHECK and REQUIRE
  • The resulting type must be convertible to bool

Fixes

• Fixed computation of benchmarking column widths in ConsoleReporter (#1885, #1886)
• Suppressed clang-tidy's cppcoreguidelines-pro-type-vararg in assertions (#1901)
  • It was a false positive trigered by the new warning support workaround
• Fixed bug in test specification parser handling of OR'd patterns using escaping (#1905)

Miscellaneous

• Worked around IBM XL's codegen bug (#1907)
  • It would emit code for destructors of temporaries in an unevaluated context
• Improved detection of stdlib's support for std::uncaught_exceptions (#1911)
