a33b93f7f1 sketch out the planned instruction alias mechanism, add some comments about
how the push/pop mnemonic aliases are wrong.

it would be a bit too big :-)

0f899c78e1 Resolve a terrible hack in tblgen: instead of hardcoding
"In32BitMode" and "In64BitMode" into tblgen, allow any
predicate that inherits from AssemblerPredicate.

693173feef 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.

10d3191cf1 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.

14e8d71cc9 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.
