llvmpipe: Fix build with LLVM 2.8

Commit 8d9778589f4b3a174e884338adb0fe1bdeca5eb7 added all-targets to the
LLVM_COMPONENTS list, but this component does not exist with LLVM 2.8.

Adding all-targets is not necessary for any drivers, and it seems to be
left over from earlier versions of the commit mentioned above.

configure.ac: Use amdgpu component for LLVM 3.2

The amdgpu component actually does exist.  I must have been using an
older version of llvm-config by accident when I first made this change.

r600g: Re-enable growing of the compute memory pool

r600g: Fix bug when adding new items to the compute memory pool

The items are ordered in the item list by their offsets, with the lowest
offset coming first in the list.  The old code was assuming that new
items being added to the list would always have a greater offset than
the first item in the list, however this is not always the case.

mesa/tests: Sanity check the ES2 dispatch table

This test is only built when shared-glapi is used.  Because of changes
elsewhere in the tree that were necessary to make shared-glapi work
correct with GLX, it's not feasible to make the test function both ways.

The list of expected functions originally came from the functions set by
api_exec_es2.c.  This file no longer exists in Mesa (but api_exec_es1.c
is still generated).  It was the generated file that configured the
dispatch table for ES2 contexts.  This test verifies that all of the
functions set by the old api_exec_es2.c (with the recent addition of VAO
functions) are set in the dispatch table and everything else is a NOP.

When adding ES2 (or ES3) extensions that add new functions, this test
will need to be modified to expect dispatch functions for the new
extension functions.

size.
