d57d9e862d eliminate the old InstFormatName which is always "AsmString",
simplify CodeGenInstruction. No functionality change.

4d8fbad207 Add a specialization for 'long', a hole in the set of fundamental
specializations provided here. This is a little annoying because its size
changes from platform to platform. If possible, I may follow up with a patch
that uses standard constants to simplify much of this, but assuming for now
that was avoided for a reason.

49227ad505 Resolve a terrible hack in tblgen: instead of hardcoding
"In32BitMode" and "In64BitMode" into tblgen, allow any
predicate that inherits from AssemblerPredicate.

15e92ddd01 Implement (and document!) support for MnemonicAlias's to have Requires
directives, allowing things like this:

def : MnemonicAlias<"pop", "popl">, Requires<[In32BitMode]>;
def : MnemonicAlias<"pop", "popq">, Requires<[In64BitMode]>;

Move the rest of the X86 MnemonicAliases over to the .td file.

cfdc3382c9 Remove deprecated macro names. Hopefully this will unbreak the
smooshlab build.  The breakage seems to be due to a collision
between LLVM's ATTRIBUTE_UNUSED and gcc's which was previously
hidden due to header files being included in a lucky order.

7a1dadd47d This is a prototype of an experimental register allocation
framework. It's purpose is not to improve register allocation per se,
but to make it easier to develop powerful live range splitting. I call
it the basic allocator because it is as simple as a global allocator
can be but provides the building blocks for sophisticated register
allocation with live range splitting. 

A minimal implementation is provided that trivially spills whenever it
runs out of registers. I'm checking in now to get high-level design
and style feedback. I've only done minimal testing. The next step is
implementing a "greedy" allocation algorithm that does some register
reassignment and makes better splitting decisions.
