[Andreas Boll]

From: Brian Paul <brianp at vmware.com>

Bump limit from 32 to 128.

Fixes http://bugs.freedesktop.org/show_bug.cgi?id=58545
(cherry picked from commit 1b6ba9c4c840e291cbbe19a8601b56d1d103179c)

Fixes the following crashing piglit tests on 9.0 with llvmpipe:

./bin/varying-packing-simple mat2x4 array -auto -fbo
./bin/varying-packing-simple mat2x4 separate -auto -fbo
./bin/varying-packing-simple mat4 array -auto -fbo
./bin/varying-packing-simple mat4 separate -auto -fbo
./bin/varying-packing-simple vec4 array -auto -fbo
./bin/varying-packing-simple vec4 separate -auto -fbo

Error:
gallivm/lp_bld_tgsi_info.c:75:analyse_src: Assertion `src->Index < (sizeof(ctx->imm)/sizeof((ctx->imm)[0]))' failed.

Regression on the 9.0 branch introduced with
8ff8c91 mesa: bump MAX_VARYING to 32
