Tim Northover 5adb224bc2 [asan] relax strstr tests.
Darwin's implementation of strstr seems to trigger slightly different failure
modes from Linux since it calls strncmp. All messages seem about equally useful
and correct, so I relaxed the tests so Darwin can pass.

Reid Kleckner 85220d0218 Use %env_asan_opts= substitution instead of 'env ASAN_OPTIONS=$ASAN_OPTIONS'
Summary:
The lit internal shell is used by default on Windows, and it does not
support bash variable expansion. Because bash variable expansion
interacts with tokenization, it is prohibitively difficult to make the
existing lit shell do general shell variable expansion.

The most common use of shell variables in the asan tests is to add
options to the default set of options set by lit.cfg. We can avoid the
need for variable expansion with a substitution that expands to 'env
ASAN_OPTIONS=<defaults:>'.

This has the side benefit of shortening the RUN lines, so it seemed
better than implementing limited variable expansion in lit.

Filipe Cabecinhas 91244924cb [ASan] Test churn for setting ASAN_OPTIONS=symbolize_vs_style=false
Summary:
This commit adds symbolize_vs_style=false to every instance of
ASAN_OPTIONS in the asan tests and sets
ASAN_OPTIONS=symbolize_vs_style=false in lit, for tests which don't set
it.

This way we don't need to make the tests be able to deal with both
symbolize styles.

This is the first patch in the series. I will eventually submit for the
other sanitizers too.

We need this change (or another way to deal with the different outputs) in
order to be able to default to symbolize_vs_style=true on some platforms.

Adding to this change, I'm also adding "env " before any command line
which sets environment variables. That way the test works on other host
shells, like we have if the host is running Windows.
