cefc38659a Assume .cfi_startproc is the first thing in a function. If the function is 
externally visable, create a local symbol to use in the CFE. If not, use the
function label itself.

Fixes PR10420.

8a625cebd2 Add the 'resume' instruction for the new EH rewrite. 
This adds the 'resume' instruction class, IR parsing, and bitcode reading and
writing. The 'resume' instruction resumes propagation of an existing (in-flight)
exception whose unwinding was interrupted with a 'landingpad' instruction (to be
added later).

7b77f35a1b Add an isSSA() flag to MachineRegisterInfo. 
This flag is true from isel to register allocation when the machine
function is required to be in SSA form.  The TwoAddressInstructionPass
and PHIElimination passes clear the flag.

The SSA flag wil be used by the machine code verifier to check for SSA
form, and eventually an assertion can enforce it in +Asserts builds.
This will catch the common target error of creating machine code with
multiple defs of a virtual register.

Create a std::string wrapper for use as a DenseMap key.  DenseMap is
not safe in generate with strings, so this wrapper indicates that only
strings guaranteed not to have certain values should be used in the
DenseMap.

6f2419f1a2 Misc optimizer+codegen work for 'cmpxchg' and 'atomicrmw'. They appear to be 
working on x86 (at least for trivial testcases); other architectures will
need more work so that they actually emit the appropriate instructions for
orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC,
Mips, and Alpha backends need such changes.)

f6797ffc9a LangRef and basic memory-representation/reading/writing for 'cmpxchg' and 
'atomicrmw' instructions, which allow representing all the current atomic
rmw intrinsics.

The allowed operands for these instructions are heavily restricted at the
moment; we can probably loosen it a bit, but supporting general
first-class types (where it makes sense) might get a bit complicated,
given how SelectionDAG works.

As an initial cut, these operations do not support specifying an alignment,
but it would be possible to add if we think it's useful. Specifying an
alignment lower than the natural alignment would be essentially
impossible to support on anything other than x86, but specifying a greater
alignment would be possible.  I can't think of any useful optimizations which
would use that information, but maybe someone else has ideas.

Optimizer/codegen support coming soon.

389cb9d8c6 During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

9286081ccc Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters. 
They mostly mirror the ArrayRef constructors, with two exceptions:
 * There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
 * There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)

e0fc4019f9 Update MCParsedAsmOperand debug methods. 
Update the debug output interface for MCParsedAsmOperand to have a print()
method which takes an output stream argument, an << operator which invokes
the print method using the given stream, and a dump() method which prints
the operand to the dbgs() stream. This makes the interface more consistent
with the rest of LLVM, and more convenient to use at the debugger command
line.
