c9d44f0d9c Add simple cost model to perfect shuffle. Currently we're doing just greedy search for cost instead of (proper) dynamic programming approach.

e55db74152 The attached patches attempt to fix cross builds. For example, if you
try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

Patch by Sandeep Patel!

7bee3271e8 rewrite FindStringInBuffer to use an explicit loop instead of
trying to wrap strstr which is just too inconvenient.  Make it
use a StringRef to avoid ".c_str()" calls.

There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained.  It is easy to add this now and should help
catch errors in the future.

7417b761c2 Add 'isCodeGenOnly' bit to Instruction .td records.
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

72fa87f0cf llvm-mc/AsmParser: Add hack to ignore Int_* and *_Int instructions for now, to
make it easier to see interesting ambiguities.
 - Also, check that user doesn't try to redefine the super class. This is a wart
   in the current design, in that assembler match classes aren't explicitly
   declared somewhere (so there isn't a unique place to declare the super
   class). This should probably be fixed.

2b54481a77 llvm-mc/AsmParser: Separate instruction ordering for ambiguity detection.
- We want the ordering operation to be simple, since we run it on every
   match. The old ordering is also not a strict weak ordering when there are
   ambiguities, which makes MSVC unhappy.

 - While we are at it, detect all ambiguities instead of just the adjacent
   ones. There are actually 655, for X86.

a3741fa28b llvm-mc/AsmMatcher: Improve match code.
- This doesn't actually improve the algorithm (its still linear), but the
   generated (match) code is now fairly compact and table driven. Still need a
   generic string matcher.

 - The table still needs to be compressed, this is quite simple to do and should
   shrink it to under 16k.

 - This also simplifies and restructures the code to make the match classes more
   explicit, in anticipation of resolving ambiguities.
