babf0569e2 Teach TableGen to infer missing register classes.
The set of register classes should be closed under sub-register
operations and intersections. That will allow the register allocator to
model combinations of constraints accurately.

This patch implements the easiest form of register class inference:  For
every register class, and for every sub-register SubIdx, the subset of
registers in RC that have a SubIdx sub-register should also be a register
class.

This does create some new register classes for the targets in the tree:

ARM gets a new QQQQPR_with_ssub_0.  This class was omitted from the .td
file on purpose because it only has two registers.  InstrEmitter and
RegisterCoalescer have safeguards against selecting too small register
classes, so it is harmless.

PowerPC gets a G8RC_with_sub_32 class because LR is not a sub_32
sub-register of LR8.  I think that might be an omission?

X86 puts RIP in the GR64 class, and since that register doesn't have
8-bit sub-registers, we get:

  GR64_with_sub_8bit
  GR64_TC_with_sub_8bit
  GR64_NOREX_with_sub_8bit
  GR64_TC_with_sub_8bit_hi

The various CodeGen classes have already been fixed so adding new
register classes should not affect compile time.

6fea31e730 TableGen: Privatize CodeGenRegisterClass::TheDef and Name.
When TableGen starts creating its own register classes, the synthesized
classes won't have a Record reference.  All register classes must have a
name, though.

f987425657 tblgen: add preprocessor as a separate mode
This patch adds a preprocessor that can expand nested for-loops for
saving some copy-n-paste in *.td files.

The preprocessor is not yet integrated with TGParser, and so it has
no direct effect on *.td inputs.  However, you may preprocess an td
input (and only preprocess it).

To test the proprecessor, type:
  tblgen -E -o $@ $<

f7e4aefd0f Check-pointing the new SjLj EH lowering.
This code will replace the version in ARMAsmPrinter.cpp. It creates a new
machine basic block, which is the dispatch for the return from a longjmp
call. It then shoves the address of that machine basic block into the correct
place in the function context so that the EH runtime will jump to it directly
instead of having to go through a compare-and-jump-to-the-dispatch bit. This
should be more efficient in the common case.
