Originally, self reference checking made a double pass over some expressions
to handle reference type checking.  Now, allow HandleValue to also check
reference types, and fallback to Visit for unhandled expressions.

Naked functions don't have prologues or epilogues, so doing
codegen for anything other than inline assembly would be completely
hit or miss.

For naked functions with parameters, Clang would still emit stores in the prologue
that would clobber the stack, because LLVM doesn't set up a stack frame. (This
shows up in -O0 compiles, because the stores are optimized away otherwise.)

For example:

  __attribute__((naked)) int f(int x) {
    asm("movl $42, %eax");
    asm("retl");
  }

Would result in:

  _Z1fi:
  movl    12(%esp), %eax
  movl    %eax, (%esp)    <--- Oops.
  movl    $42, %eax
  retl

before retrying the initialization to produce diagnostics. Otherwise, we may
fail to produce any diagnostics, and silently produce invalid AST in a -Asserts
build. Also add a note to this codepath to make it more clear why we were
trying to create a temporary.

If control falls off the end of a function after an __asm block, MSVC
assumes that the inline assembly filled the EAX and possibly EDX
registers with an appropriate return value. This functionality is used
in inline functions returning 64-bit integers in system headers, so we
need some amount of compatibility.

This is implemented in Clang by adding extra output constraints to every
inline asm block, and storing the resulting output registers into the
return value slot. If we see an asm block somewhere in the function
body, we emit a normal epilogue instead of marking the end of the
function with a return type unreachable.

Normal returns in functions not using this functionality will overwrite
the return value slot, and in most cases LLVM should be able to
eliminate the dead stores.

Fixes PR17201.

Summary:
This allows us to easily find them in the backend after the aggregates have
been lowered to other types. This is important on big-endian targets using
the N32/N64 ABI's since these ABI's must shift small structures into the
upper bits of the register.

Summary:
Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
 - Make some code type agnostic and move it to the cpp file.
 - Return a DynTypedMatcher instead of storing the object in MatcherOps.

This change reduces the number of symbols generated in Registry.cpp by
~19%, the object byte size by ~17% and the compilation time (in non-release mode) by ~20%.

They are returned indirectly which causes the other arguments to move to

With this, utils/ABITest does not discover any failing cases in the first
