This patch makes use of two of the new ioctls added in MGA DRM version
3.2. Specifically, the DRM_MGA_SET_FENCE and DRM_MGA_WAIT_FENCE
ioctls are used in mgaWaitForFrameCompletion. As a result the MMIO
register region and the primary DMA region are *not* mapped (if DRM
3.2 is available).
This patch does *not* make use of the new get_param query was added to
differentiate between G4x0 cards and G550 cards. That is left to a
future update.

vertex_program struct.
Allow switching between regular and vertex_program implementations
of fixed function TNL with the MESA_TNL_PROG environment var
(previously this required recompilation).
Ensure program compilation only references program data, not the
wider context. This means that compiled programs only need to be
invalidated when the program string changes, not on other state
changes.
distilled from the current state.
Maintain a list of vertex programs for various different tnl states
indexed by these state keys.
This cuts down the number of vertex programs generated and means that
time spent optimizing vertex programs for execution isn't wasted each
time the state changes.

Works for the arbfplight demo at least.
- Expand operand argument specifiers so that all registers and
parameters can be referenced directly. Remove old PAR/PRL
instructions.
- No 3 operand instructions, translate MAD -> MUL, ADD. (No room for
3 full operands in instruction struct).
- Translate SWZ instructions into 1 or 2 reduced swizzles at compile
time.
- Add hardwired code for moving input and output values to/from the
register file. Drop old INx, OUT instructions.
