This forces clang to avoid use init_array for all initialization rather than
splitting the initialization between init_array and ctors.

Local builds do this anyway, but for some reason the builds on go/ab do not.
Setting this flag makes the builds consistent (and unbroken on JB-MR1).

I already checked this in on cloud-android-current-release because I wanted
to test it before submitting.

The blitter now supports integer types. This means:
- It supports conversions to/from integer types from/to
  other already supported types.
- It supports integer to integer conversions without going
  to an intermediate float format.

Also added a Blitter::GetScale() function to avoid having
2 instances of the same switch statement in the code and
added the read/write utility functions. The final Blitter
code is not longer peppered with switch statements and is,
hopefully, easier to read that way.
