46742a4771 Add some missing X86-specific asm constraint letters, and fix
some bugs in setting allowsRegister on the ones there.

db6d5cb892 Implement PR6845. We allow matching constraints to have different
input and output types when the smaller value isn't mentioned in the
asm string.  Extend this support from integers to also allowing 
fp values to be mismatched (if not mentioned in the asm string).

eaa2778f27 fix a buildbot failure, this was passing for me because the
'%t' file was left around on my disk.  doh.

aabec2fb84 merge asm-2.c into asm.c, remove asm-inout.c because it is
XFAIL and already tracked in bugzilla.

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).

8b57697954 Eliminate &&s in tests.
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

previously we only recognized it on inputs.

97ea867690 MultiTestRunner: Validate '&&' at the end of RUN lines.
- This is just to normalize, these will go away soon hopefully.

Added all the missing '&&'s that have crept in. :)

59c3a9cd54 add support for tying asm operands where the result is smaller than
the input.  This is part of PR3373.

10f221f321 implement support for asm outputs targetting non-simple lvalue destinations
like bitfields.  incidentally llvm-gcc crashes on this sort of thing also. :)

f85a938985 Fix PR3682 by just disabling a broken assertion. This check should be
done in sema, and is reflected by the existing PR3258.  In the meantime,
fix PR3682 by disabling a bogus assertion (which doesn't account for + 
operands).

time handle + operands in operand counting, fixing asm.c:t7 to
expand into $2 instead of $1.
