syntactically loopify natural loops so that the GCC loop optimizer can find them. This should *dramatically* improve the performance of CBE compiled code on targets that depend on GCC's loop optimizations (like PPC)

SPECIFY a target data to initialize the CBE target with. Until now we have
...
been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed! This could improve the
performance of the CBE generated code substantially!

TargetCacheInfo has been removed; its only uses were to propagate a constant
...
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

Fixes for PR258 and PR259.

Functions with linkonce linkage are declared with weak linkage.
Global floating point constants used to represent unprintable values
(such as NaN and infinity) are declared static so that they don't interfere
with other CBE generated translation units.

Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some
...
hacks can be banished. Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs). Yaay!
