A `lit` condition line is now a comma-separated list of boolean expressions.
Comma-separated expressions act as if each expression were on its own
condition line:
For REQUIRES, if every expression is true then the test will run.
For UNSUPPORTED, if every expression is false then the test will run.
For XFAIL, if every expression is false then the test is expected to succeed.
As a special case "XFAIL: *" expects the test to fail.
Examples:
# Test is expected fail on 64-bit Apple simulators and pass everywhere else
XFAIL: x86_64 && apple && !macosx
# Test is unsupported on Windows and on non-Ubuntu Linux
# and supported everywhere else
UNSUPPORTED: linux && !ubuntu, system-windows
Syntax:
* '&&', '||', '!', '(', ')'. 'true' is true. 'false' is false.
* Each test feature is a true identifier.
* Substrings of the target triple are true identifiers for UNSUPPORTED
and XFAIL, but not for REQUIRES. (This matches the current behavior.)
* All other identifiers are false.
* Identifiers are [-+=._a-zA-Z0-9]+
