See RHS of https://codereview.chromium.org/1558903002/diff/1/nss.gyp for the
list of flags used in the gyp build.

Note that warning flags need to be in a separate config in gn to work (see e.g.
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/pdfium...)
– I suppose no platform still on NSS is on GN yet, so it's not yet a problem.
But moving this list to a config is easier when it's complete, so it makes sense
to me to mirror this.
