On Windows, the PATH env variable is used for locating dynamically
linked librarys, akin to LD_LIBRARY_PATH on Linux.
The tests that run with a dynamically linked libc++ used "--env
PATH=%{lib}" in the test config. This had the unfortunate side effect
of making other tools from PATH unavailable during the runtime of the
tests; in particular, it caused the "executor-has-no-bash" flag to be
set for all those Windows test configs (with the clang-cl static config
being the only one lacking it).
Thus, this increases the number of tests actually included in the
clang-cl dll and all mingw test configs by 9 tests.
The clang-cl static test configuration has been executing those tests
since the "--env PATH=%{lib}" was removed from that test config in
e78223e79efc886ef6f0ea5413deab3737d6d63b. (For mingw we haven't had a
need to split the test config between shared and static, which means
that the mingw static test config previously ran with --env PATH
needlessly.)
This increases the test coverage for patches like D146398 which
can't be executed in the executor-has-no-bash configs.
Change the default value of the arg.env to an empty array; when we do
pass values to the option, they get passed as an array of strings,
so make sure the variable behaves consistently when no arguments
have been passed.
