ARM/PPC/MSP430-specific code (which are the only targets that
implement the hook) can directly reference their target-specific
instrinfo classes.

This is probably not the best way to implement "Force LR to
be spilled if the Thumb function size is > 2048." do this,
it should use the branch shortening infrastructure, but I'm
just preserving functionality here.

This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.

ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

a second, unused, copy of the table from being emitted after the function
body. PR6581.

- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

in the README.txt regarding a bitfield copy.

stack realignment on ARM.
Also check for function attributes as we do on X86 as well as
make explicit that we're checking can as well as needs in this function.

-enable-no-nans-fp-math and -enable-no-infs-fp-math. All of the current codegen fp math optimizations only care whether the fp arithmetics arguments and results can never be NaN.

instructions use different values (e.g., 2-byte or 4-byte alignment).
Also fix ARMInstPrinter to print these alignments as bits instead of bytes.

instructions already have implicit defs of LR. The comment suggests that
this is intended to fix something like pr6111, but it doesn't really do
that either.

The only folding these load/store architectures can do is converting COPY into a
load or store, and the target independent part of foldMemoryOperand already
knows how to do that.
