i965/blorp: switch eu-emitter to use FS IR and fs_generator
No regressions on IVB (piglit quick + unit tests).
v2 (Paul):
- no need to patch the unit tests anymore. Original logic
was altered and unit tests updated to match the
fs-generator
- lrp emission moves from the blorp compiler core into the
emitter here (previously there was a separate refactoring
patch which is not really needed anymore as the lrp logic
got refactored when the original lrp logic got fixed).
- pass 'BRW_BLORP_RENDERBUFFER_BINDING_TABLE_INDEX' to the
generator in fs_inst::target instead of hardcoding it
