glsl ubo/ssbo: Add lower_buffer_access class

Graphics / Mesa 3D Graphics Library / Mesa - Jordan Justen [intel.com] - 10 December 2015 01:50 UTC

This class has code that will be shared by lower_ubo_reference and lower_shared_reference. (lower_shared_reference will be used to support compute shader shared variables.)

v2:
- Add lower_buffer_access.h to makefile (Emil)
- Remove static is_dereferenced_thing_row_major from lower_buffer_access.cpp. This will become a lower_buffer_access method in the next commit.
- Pass mem_ctx as parameter rather than using a member variable (Iago)
