d2128a7ca5 cleanup this code, making it more "llvm-like".
Add comments to reset indicating that it deletes its pointer.
Add a new take() method, which can be used to get the pointer
without it being deleted.

fd7b326bea Make invokes of inline asm legal. Teach codegen
how to lower them (with no attempt made to be
efficient, since they should only occur for
unoptimized code).

43ad6b3e0d Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

d7610e16fc Fix the JIT encoding of cmp*ss, which aborts with this assertion currently:
X86CodeEmitter.cpp:378: failed assertion `0 && "Immediate size not set!"'

I *think* this is right, but Evan, please verify.  It also looks like
CMPSDrr and maybe others are missing this info.  Evan, plz investigate.

ece2c04d53 Make instcombine promote inline asm calls to 'nounwind'
calls.  Remove special casing of inline asm from the
inliner.  There is a potential problem: the verifier
rejects invokes of inline asm (not sure why).  If an
asm call is not marked "nounwind" in some .ll, and
instcombine is not run, but the inliner is run, then
an illegal module will be created.  This is bad but
I'm not sure what the best approach is.  I'm tempted
to remove the check in the verifier...

8a43e9e5d7 Teach the interpreter to read and write memory in the
endianness of the target not of the host.  Done by the
simple expedient of reversing bytes for primitive types
if the host and target endianness don't match.  This is
correct for integer and pointer types.  I don't know if
it is correct for floating point types.
