19ccfc3d63 have GetAliasRequiredFeatures get its features from 
AsmMatcherInfo so we don't have two places that know the
feature -> enum mapping.  No functionality change.

17980631fb simplify code that creates SubtargetFeatureInfo, ensuring that features 
that are only used by MnemonicAliases will be found.

d4ea8ee6f2 fix a fixme in stringmatcher, having it generate nice looking code if the 
'tomatch' code contains \n's.

aace31ce48 fix typos and some serious bugs in feature handling (but not for 
cases that are currently exercised).  Thanks to Frits van Bommel for
the great review!

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.

7c61e4bca2 implement (and document!) the first kind of MC assembler alias, which 
just remaps one mnemonic to another.  Convert a few of the X86 aliases
from .cpp to .td code.

bd838d16e5 fix the asmmatcher generator to handle targets with no RegisterPrefix 
(like ARM) correctly.  With this change, we can now match "bx lr"
because we recognize lr as a register.

44d2802e1d Shifter ops are not always free. Do not fold them (especially to form 
complex load / store addressing mode) when they have higher cost and
when they have more than one use.

30f6744f05 First part of refactoring ARM addrmode2 (load/store) instructions to be more 
explicit about the operands. Split out the different variants into separate
instructions. This gives us the ability to, among other things, assign
different scheduling itineraries to the variants. rdar://8477752.

005aa1c020 Teach FileCheck to handle trailing CHECK-NOT patterns. 
A CHECK-NOT pattern without a following CHECK pattern simply checks that the
pattern doesn't match before the end of the input file.

You can even have only CHECK-NOT patterns to check that strings appear nowhere
in the input file.

394bc160f9 Allow targets to optionally specify custom binary encoder functions for 
operand values. This is useful for operands which require additional trickery
to encode into the instruction. For example, the ARM shifted immediate and
shifted register operands.

8fae045502 When figuring out which operands match which encoding fields in an instruction, 
try to match them by name first. If there is no by-name match, fall back to
assuming they are in order (this was the previous behavior).

c9709f154d Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.
