Arthur Eubanks 92a77f4b5e [NewPM][ASan] Make ASan tests work under NPM
Under NPM, the asan-globals-md analysis is required but cannot be run
within the asan function pass due to module analyses not being able to
run from a function pass. So this pins all tests using "-asan" to the
legacy PM and adds a corresponding RUN line with
-passes='require<asan-globals-md>,function(asan)'.

Now all tests in Instrumentation/AddressSanitizer pass when
-enable-new-pm is by default on.

Tests were automatically converted using the following python script and
failures were manually fixed up.

import sys
for i in sys.argv:
    with open(i, 'r') as f:
        s = f.read()
    with open(i, 'w') as f:
        for l in s.splitlines():
            if "RUN:" in l and ' -asan -asan-module ' in l and '\\' not in l:
                f.write(l.replace(' -asan -asan-module ', ' -asan -asan-module -enable-new-pm=0 '))
                f.write('\n')
                f.write(l.replace(' -asan -asan-module ', " -passes='require<asan-globals-md>,function(asan),module(asan-module)' "))
                f.write('\n')
            elif "RUN:" in l and ' -asan ' in l and '\\' not in l:
                f.write(l.replace(' -asan ', ' -asan -enable-new-pm=0 '))
                f.write('\n')
                f.write(l.replace(' -asan ', " -passes='require<asan-globals-md>,function(asan)' "))
                f.write('\n')
            else:
                f.write(l)
                f.write('\n')
