Behdad Esfahbod ae8719eb59 [ragel] Switch to -T1 output instead of -F1 
Fedora upgraded to ragel 7, which is buggy if char is signed.
Switching to -G2 output fails with sign-compare error:

../../src/hb-buffer-deserialize-json.hh:107:12: error: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘const char’ [-Werror=sign-compare]
    if ( 9u <= ( (*( p))) && ( (*( p))) <= 13u ) {
         ~~~^~~~~~~~~~~~~

Switching to -T1 for now.  It actually results in smaller code,
at the expense of some binary searching instead of flat tables.
In the not distant future, we might actually generate two different
outputs and choose between depending on size-optimize options.

Behdad Esfahbod abc82b493e Add Ragel-generated files to git 
I know it's bad form; I know I've said no to this multiple times...
But this is part of an experiment to see if we can make rolling HarfBuzz
into Chrome much faster. That will give us a lot more testing exposure
that currently Chrome does.

Doing this while those files are still considered ignored by our
gitignore rules; will see how that flies.
