Not all platforms supports sighandler_t, so I changed it to use the older
return value from signal() (which should be the same type; it's just not
typedef'd).
This fixes the build on Solaris.

Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

Also modified some code to not access the GlobalAddress map directly.

Minor code cleanups.  The only bugfix is to the UR_DEBUG stuff which didn't
compile when enabled.

Updated from files in llvm/autoconf.  This was done immediently following
the renaming of aclocal.m4 to acinclude.m4.

Moved aclocal.m4 to acinclude.m4.  To re-generate the configure script,
do the following:
% cd llvm/autoconf
% aclocal
% autoconf -o ../configure

This changes facilitaties the following:
1) It should be easier to incorporate new autoconf macros.
2) It allows for conversion to Automake (should we ever desire it).

Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.

it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

Modified the linker so that it always links in an object from an archive
