mesa/glsl: rename preprocess to glcpp_preprocess
This symbol with dricore escapes into the namespace, its too generic,
we should prefix it with something just to be nice.
Should be applied to stable + 9.0

glcpp: fix abuse of yylex
So glcpp tried to workaround yylex its own way, but failed,
do it properly.
This fixes another crash found after fixing the first crash.
this is a candidate for 9.0 and stable branches

mesa: use a prefix for the program lex
This avoids us making a global yylex symbol which will interfere will
all sorts of apps.
with libdricore which can't do symbol visibility currently we pollute
the namespace with this.
This is a candidate for 9.0 & stable branches.

mklib: clean up abi flags for x86 targets
The current code is duplicated in two places and relies on `uname` to
detect the flags. This is no good for cross-compiling, and the current
logic uses -m64 for the x32 ABI which breaks things.
Unify the code in one place, avoid `uname` completely, and add support
for the new x32 ABI.

i965: Fix out-of-order sampler unit usage in ARB fragment programs.
ARB fragment programs use texture unit numbers directly, unlike GLSL
which has an extra indirection. If a fragment program only uses one
texture assigned to GL_TEXTURE1, SamplersUsed will only contain a single
bit, which would make us only upload a single surface/sampler state
entry. However, it needs to be the second entry.
Using _mesa_fls() instead of _mesa_bitcount() solves this. For ARB
programs, this makes num_samplers the ID of the highest texture unit
used. Since GLSL uses consecutive integers assigned by the linker,
_mesa_fls() should give the same result as _mesa_bitcount()..
Fixes a regression since 85e8e9e000732908b259a7e2cbc1724a1be2d447,
which caused GPU hangs in ETQW (and probably others), as well as
breaking piglit test fp-fragment-position.
v2: Add a comment, as suggested by Matt.

commit 66e8f863d34fc8b8f7602c45bb3230fe663d4eb0

mesa: Add a _mesa_fls() function to find the last bit set in a word.
ffs() finds the least significant bit set; _mesa_fls() finds the /most/
significant bit.
v2: Make it an inline function in imports.h, per Brian's suggestion.
