b3d5822e93 util: add gcc version check for builtins 
Looks like only next_power_of_two, logbase2 and bitcount use builtins
requiring gcc 3.4, so maybe everything else compiles with older gcc.

894db40f12 util: better logbase2/next_power_of_two implementations 
Use __builtin_clz when available for logbase/next_power_of_two,
and replace next_power_of_two with faster implementation otherwise.

970726dd6f u_prim: convert u_trim_pipe_prim to table driven. 
This makes this function not be an always miss for the branch predictor.

Noticed using cachegrind, makes a minor difference to gears numbers on r600g.

51095f74cf u_vbuf_mgr: fix max_index computation once again 
See how I compute and use the 'unused' variable in the code.
It's crucial for getting max_index right.

Fixed with the help of apitrace.
(bisecting the problematic draw call manually was not fun though)

This should fix:

1271424615 mesa, util: move RGB9E5 conversion functions to gallium/util 
Also use MAX3 and incorporate Ian's suggestion in texformat.c.

I don't think wrapping u_format_rgb9e5.h in another header and thus making it
more complicated is worth it.

ebe304fa54 gallium: list use inline function to avoid macro shot coming 
Macro can lead to hard to debug list bugs. For instance consider
the following :
LIST_ADD(item, list->prev)
3 instruction of the macro became :
(list->prev)->next->prev = item
which is equivalent to :
list->prev = item
Thus list prev field changes and next instruction in the macro
(list->prev)->next = item
became :
item->next = item
And you endup with list corruption, other case lead to similar
list corruption. Inline function are not affected by this short
coming

this utility and avoid sw vertex fallbacks if pstipple is enabled.
