AsmOperandInfo. No functionality change for valid code.

I am sufficiently unaquainted with doxygen to
defer the markup to someone with more experience.

using the 'volatile' qualifier. This should not have any operational consequences
on code, because tags should always be stripped off (giving a non-volatile pointer)
before dereferencing. The new qualification is there to catch some attempts to use
tagged pointers in a context where an untagged pointer is appropriate.
Notably this approach does not catch dereferencing of tagged pointers, but helps
in separating the two concepts a bit.

because it declares a std::vector<MachineMove>, and strict
concept checking requires the definition of MachineMove to be
available.

SmallVector better conform to the Container concept.

i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

- Move the EH landing-pad code and adjust it so that it works
with FastISel as well as with SDISel.
- Add FastISel support for @llvm.eh.exception and
@llvm.eh.selector.

builtins do not: rounds* has an extra operand. Fixes

Plugins can be now compiled in with a slight Makefile change.
For example, to compile the new Clang driver, use:
cd $LLVMC2_DIR
make TOOLNAME=ccc2 BUILTIN_PLUGINS=Clang
