This is to avoid issues with compilation flags changing during development while
the ANGLE version does not change. It's easy to forget to flush Chrome's disk
cache.

Seems like a prudent thing to do.

Please also make sure BUILD_REVISION in version.h is updated so that
VERSION_DWORD reflects that this is a new binary format.

Oh and this was the issue with the dx11proto branch! I thought I was changing
the optimization level when it was really using old cached level 1 binaries from
a previous run.

Excellent! I was wondering about that, but forgot to ask during the review.
