8e27c96159 TableGen: AsmMatcher diagnostic when missing instruction mnemonic.
Previously, if an instruction definition was missing the mnemonic,
the next line would just assert(). Issue a real diagnostic instead.

a93090ccd9 Order register classes by spill size first, members last.
This is still a topological ordering such that every register class gets
a smaller enum value than its sub-classes.

Placing the smaller spill sizes first makes a difference for the
super-register class bit masks. When looking for a super-register class,
we usually want the smallest possible kind of super-register. That is
now available as the first bit set in the bit mask.

7855ec62c3 Remove TargetRegisterClass::SuperRegClasses.
This manually enumerated list of super-register classes has been
superceeded by the automatically computed super-register class masks
available through SuperRegClassIterator.

1a2a19dd3c Add TargetRegisterClass::getSuperRegIndices().
This is a pointer into one of the tables used by
getMatchingSuperRegClass(). It makes it possible to use a shared
implementation of that function.

6a0ed18532 Emit SuperRegMasks as part of the existing SubClassMask arrays.
The RC->getSubClassMask() pointer now points to a sequence of register
class bit masks. The first bit mask is the normal sub-class mask. The
following masks are super-reg class masks used by
getMatchingSuperRegClass().

f92be238d6 Compress tables for getMatchingSuperRegClass().
Many register classes only have a few super-registers, so it is not
necessary to keep individual bit masks for all possible sub-register
indices.

309076ff76 Don't override subreg functions in targets without subregisters.
Some targets have no sub-registers at all. Use the TargetRegisterInfo
versions of composeSubRegIndices(), getSubClassWithSubReg(), and
getMatchingSuperRegClass() for those targets.

14ce6fac24 ARM: improved assembler diagnostics for missing CPU features.
When an instruction match is found, but the subtarget features it
requires are not available (missing floating point unit, or thumb vs arm
mode, for example), issue a diagnostic that identifies what the feature
mismatch is.

c1922c72ad TableGen support for auto-generating assembly two-operand aliases.
Assembly matchers for instructions with a two-operand form. ARM is full
of these, for example:
  add {Rd}, Rn, Rm  // Rd is optional and is the same as Rn if omitted.

The property TwoOperandAliasConstraint on the instruction definition controls
when, and if, an alias will be formed. No explicit InstAlias definitions
are required.

75338097c7 Remove llvm-ld and llvm-stub (which is only used by llvm-ld).
llvm-ld is no longer useful and causes confusion and so it is being removed.

* Does not work very well on Windows because it must call a gcc like driver to
  assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
  ld, or fully replaced by Clang.

I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.
