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.

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).

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

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));
