[PATCH] [IR/AsmWriter] Output escape sequences if the first character isdigit()

[Filipe Cabecinhas]

I could add some more stuff to FileCheck in that test, but am not 100% sure on what the best way to do it.

If it's safe to assume the output it currently has (!{} becomes !2, and some other "abbreviations" appear), I can do a verbatim check, but it would basically be checking copy+paste.
Comments on this?
