Bug 1230701 added the 1<<30 flag bit to nsCSSProps' kFlagsTable.

We have 1 bit left (1u << 30), after which we'll need to increase the size of the flag fields in kFlagsTable to 64-bits if we want to add any more flags.

Attached patch fix v1Splinter Review
(We don't need to take this patch quite yet, but we may need to do so soon.)
(BTW: I filed this because I initially misread a build warning about a flag that I'm adding in bug 1208344, with value 1<<31. Turns out that flag value (for the highest-order bit) is basically-fine & doesn't need this bug, but to avoid a build warning, I just needed to specify the flag value as 1u<<31 (with a "u") or else the compiler complains about storing -infinity in a _u_int32.

After that bit is added, though, we'll need this bug (to increase the number of bits) if we want any more flags.
