8cb9a3b13f remove the MAI argument to MCExpr::print and switch overthing to use << when printing them.

10b318bcb3 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

c0dba723d1 now that mangler is in libtarget, it can use MCAsmInfo instead of clients 
having to pass various fields from it in.  Simplify.

93ae407ec3 When checking for sret-demotion, it needs to use legal types. When using the return value of an sret-demoted call, it needs to use possibly illegal types that match the declared Type of the callee.

ac931c011f Add some debug routines to SelectionDAG to dump full DAGs. 
print/dumpWithDepth allows one to dump a DAG up to N levels deep.
dump/printWithFullDepth prints the whole DAG, subject to a depth limit
on 100 in the default case (to prevent infinite recursion).

Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly
what the non-matching DAG looks like.

3a32865d58 Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast). 
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

bfdcf3bd49 Change pre-regalloc tail duplication to only duplicate indirect branch blocks. 
The pre-regalloc pass caused some regressions in both compile time and
performance of the generated code, and it did not improve performance, except
for indirect branches.  I also moved the check for single-block loops to speed
up the common case when running the taildup pass before reg allocation.

9f82da7cbf Dwarf EH prepare needs to be run after SjLj prepare. Otherwise, 
catch info can get misplaced when a selector ends up more than one block
removed from the parent invoke(s). This could happen when a landing pad is
shared by multiple invokes and is also a target of a normal edge from
elsewhere.

dfbcb8c38b use the new form of getNameWithPrefix, not makeNameProper. 
Among other things, this would do very weird things if the 
basic block name had (e.g.) a space in it on darwin:
makeNameProper would add quotes, then the mcsymbol would 
escape the quotes.

4813035b72 change Mangler::makeNameProper to return its result in a SmallVector 
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

7da9ecf967 Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg. 
For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

really does need to be a vector type, because
TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
and it needs to be able to distinguish between vectors and scalars.

Also, fix some more issues with legalization of vector casts.

d40d03e1bd Teach dag combine to fold the following transformation more aggressively: 
(OP (trunc x), (trunc y)) -> (trunc (OP x, y))

Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel.

This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places.

Must be replaced with this when substituting physical registers:

b31defe94c Remove livein checks from machine code verifier. 
A phi operand that is implicitly defined in a predecessor becomes an undefined
register after phi elimination. This causes a lot of false positives when the
verifier is checking if live-in registers are live-out from all predecessors.

Removing the verifier checks seems like a better solution than insisting on
IMPLICIT_DEF instructions in predecessor blocks.

eeb3a00b84 Change SelectCode's argument from SDValue to SDNode *, to make it more

This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.
