Sean Callanan 03549ee5af Added support for ARM disassembly to edis. 
I also added a rule to the ARM target's Makefile to
build the ARM-specific instruction information table
for the enhanced disassembler.

I will add the test harness for all this stuff in
a separate commit.

Chris Lattner 1e45789ee0 introduce a new recoverable error handling API to LLVMContext 
and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)

Dan Gohman d006ab90dd Generalize IVUsers to track arbitrary expressions rather than expressions 
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.

This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.

This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.

Chris Lattner 3b9f02a2aa Three changes: 
1. Introduce some enums and accessors in the InlineAsm class
   that eliminate a ton of magic numbers when handling inline
   asm SDNode.
2. Add a new MDNodeSDNode selection dag node type that holds
   a MDNode (shocking!)
3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
   metadata, propagating it to the instruction emitter, which
   drops it.

No functionality change.

Chris Lattner 97c4cb8947 enhance SMDiagnostic to also maintain a pointer to the SourceMgr. 
Add a simplified constructor for clients that don't have locations
like "file not found" errors.

Jakob Stoklund Olesen 2ae30e864d Avoid overflowing a signed integer which triggers undefined behaviour. 
Overflowing an unsigned integer is fine and behaves as you would expect.
Also fix a pasto, allowing SignExtend64 to take a 64-bit argument.

Douglas Gregor 41e692dcf1 Introduce MaybeOwningPtr, a smart pointer that may (or may not) have 
ownership over the pointer it contains. Useful when we want to
communicate ownership while still having several clients holding on to
the same pointer *without* introducing reference counting.
