Bill Wendling c4fc3a2ba5 Emit an error message instead of crashing when dereferencing an incomplete pointer type.
If the ASM statement is dereferencing an incomplete pointer type, issue an error
instead of crashing.

Fariborz Jahanian f85f338634 c: privide deprecated warning when __private_extern__ storage
specifier is unsed in a declaration; as it may not make the symbol
local to linkage unit as intended. Suggest using "hidden" visibility 
attribute instead. // rdar://7703982

Eric Christopher af6431077c Add support for AVX registers to clang inline asm. Add a small testcase
and update the Sema testcase with a register that we won't hit for a while
I hope.

Chris Lattner 53fa04909c make clang print types as "const int *" instead of "int const*",
which is should have done from the beginning.  As usual, the most
fun with this sort of change is updating all the testcases.

John McCall 9dfb16210e Warn on top-level 'asm volatile' (instead of misparsing it).

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Eli Friedman 45966b4671 Remove the -arch option from clang-cc: for all practical purposes, it's
redundant with -triple.

Chris Lattner cb66c73a48 If we have mismatched integer tied operands, but the operand
number is not mentioned in the asm string, let it past sema. 
Right now these are currently rejected by the llvm code generator
but this will be fixed next.

Chris Lattner 574428e4db implement PR4077: [Linux kernel] inscrutable error on inline asm input/output constraint mismatch
Before we emitted:

$ clang t.c -S -m64 
llvm: error: Unsupported asm: input constraint with a matching output constraint of incompatible type!

Now we produce:
$ clang t.c -S -m64 
t.c:5:40: error: unsupported inline asm: input with type 'unsigned long' matching output with type 'int'
  asm volatile("foo " : "=a" (a) :"0" (b));
