Based on initial patch from Stephan Schmid <stephan_2303@gmx.de>.
Basic idea is to dump the zpass count at the start and end of the query
and subtract to get the total number of visible fragments. HW writes
alternating qwords for up to 4 DBs. On the first pass, we start at
buffer address + 0; on the second pass, we start at buffer address + 8
(bytes). The resulting buffer at the end of the query looks like:
qw[0]: db0 start
qw[1]: db0 end
...
qw[6]: db3 start
qw[7]: db3 end
The MSB of each qword is the valid bit and the lower 63 bits are
the zpass count for that DB.
OQ on RV740 is disabled at the moment as it only seems to report
results for half of its DBs. This needs further investigation.

Anything that matched IDENTIFIER was strdup'ed and returned to the
parser. However, almost every case of IDENTIFIER in the parser just
dropped the returned string on the floor. Every swizzle string, every
option string, every use of a variable, etc. leaked memory.
Create a temporary buffer in the parser state (string_dumpster and
dumpster_size). Return strings from the lexer to the parser in the
buffer. Grow the buffer as needed. When the parser needs to keep a
string (i.e., delcaring a new variable), let it make a copy then.
The only leak that valgrind now detects is /occasionally/ the copy of
the program string in gl_program::String is leaked. I'm not seeing
how. :(
Tests glBlitFramebuffer() between two texture/renderbuffer surfaces.
In particular, blit from level[1] of a cube map face to a 2D texture.
Used to find/fix bug in intel do_copy_texsubimage().
See commit aef1ab1073f3e30d699b99dae17518ed48b57c72
Use src->draw_offset intead of zero. Zero usually worked, except when
the src renderbuffer is actually a texture mipmap level higher than zero.
Fixes progs/test/blitfb.c test.
This reverts commit 8810b8f671.
It turns out the i965 driver uses the intel->Fallback field as a boolean,
not as a bitmask. The intelFallback() function is a no-op in the i965
driver. It would have been nice if there were some comments about this.
I'll fix that next...
