[windows] Fix or XFAIL remaining portable test failures and enable them

[rnk]

Summary

This involved various fixes:

• Move a test that uses ulimit to Posix.

• Add a few "REQUIRES: shell" lines to tests using backtick subshell evaluation.

• The MSVC CRT buffers stdio if the output is a pipe by default. Some tests need that disabled to avoid interleaving test stdio with asan output.

• MSVC headers provide _alloca instead of alloca (go figure), so add a portability macro to the two alloca tests.

• XFAIL tests that rely on accurate symbols, we need to pass more flags to make that work.

• MSVC's printf implementation of %p uses upper case letters and doesn't add 0x, so do that manually.

• Accept "SEGV" or "access-violation" reports in crash tests.

Do you really need both kinds of quotes?

Please use identation here

#ifdef _MSC_VER
# ifdef _WIN64
#  define PTR_FMT ...

If the interception machinery works differently on Windows, just move this to Posix/ ?

Yes, the double quotes need to go through into the environment variable on Windows because filepaths expanded from %T and %S contain colons after the drive letter. Since colon is the ASAN_OPTIONS separator, it must be quoted. Using single quotes is just my preferred way of escaping the double quotes. I could use backslashes.

Basically, this isn't a shell portability issue, it's an ASAN_OPTIONS parsing portability issue.

I don't think it's impossible to intercept strtoll on Windows, so this test should pass eventually.
