Fix a bunch of 80col violations that arose from the Create API change. Tweak makefile targets to find these better.

Make use of vector load and store operations to implement memcpy, memmove, and memset. Currently only X86 target is taking advantage of these.

is bitcast to return a floating point value. The result of the instruction may
not be used by the program afterwards, and LLVM will happily remove all
instructions except the call. But, on some platforms, if a value is returned as
a floating point, it may need to be removed from the stack (like x87). Thus, we
can't get rid of the bitcast even if there isn't a use of the value.

in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.

Changed cout to DOUT, and TODOs to FIXMEs.
Other changes as per coding conventions.

DAG instruction selectors. Introudce a dedicated header file for this part:
include/llvm/CodeGen/DAGISelHeader.h

TableGen now only generates the include preprocessor directive to include this
new header.

This is a preparation for supporting multiple implementations of instruction
selectors in the future.
