add jenkins support for .wasm files

[MikeHolman]

add jenkins support for .wasm files. Note, that this is the binary format for WebAssembly, and we have a couple of these files in the wasm branch. This is causing test failures in #60

@dilijev, can you please review?

[MikeHolman]

After talking with @dilijev I will include this in same PR on top of rest of wasm changes.

While you're here, you might change the grep -v -E "..." pattern to match what's in the other file.

Namely, change this line to

git diff --name-only `git merge-base origin/master HEAD` HEAD |
    grep -v -E 'test/.*\\.js$' |
    grep -v -E '\\.cmd$' |
    grep -v -E '\\.wasm$' |
    grep -v -E '\\.baseline$' |
    xargs -I % ./jenkins.check_file_eol.sh % 

That will make it easier to make future changes to this list.

[MikeHolman]

Sure, that definitely is easier to mentally parse.

@MikeHolman I made some comments here. When you integrate this commit with your new PR, can you make these changes as well? Thanks.
