Eli Friedman 1408bc9a55 Fix Sema::CheckVectorOperands so that it doesn't try to insert a cast expression into the LHS of a compound assignment. Fixes compound assignment of various "compatible" vector types, including NEON-vector and gcc-vector types.

Eric Christopher a613f56559 With lax vector conversions (the default) make sure we convert between two
vectors that are the same size. Fix up testcases accordingly and add a new one
to make sure we still error if lax vector conversions are disabled.

Fixes rdar://8328190

Douglas Gregor bc0c79b4ab Clean up the diagnostic complaining about the element type of a vector
type so that it actually complains about the element type itself.

Douglas Gregor a3208f9e7c Vector types are not arithmetic types, either. Note that we now ban
__real myvec and __imag myvec, since they aren't all that useful (it's
just an identity function) but we might want to use them in more
restricted cases in the future (e.g., "__real mycomplexvec" could
extract the real parts of a vector of complex numbers).

Douglas Gregor c646d13054 Teach Type::isRealType() that vector types are never real types. All
of the callers of isRealType() already assumed this, and one of them
(increment/decrement) mistakenly permitted increments of vector types
because of it.

Douglas Gregor 49b4d73451 Type Type::isRealFloatingType() that vectors are not floating-point
types, updating callers of both isFloatingType() and
isRealFloatingType() accordingly. Caught at least one issue where we
allowed one to declare a vector of vectors (!), along with cleaning up
the standard-conversion logic for C++.

Douglas Gregor c68e140657 Improve diagnostics when we fail to convert from a source type to a
destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as

t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
      expected 'char *' [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:

t.c:2:9: warning: initializing 'char *' from an expression of type
      'char const [2]' discards qualifiers [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

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).

Handle rules for ExtVector + ExtVector and ExtVector + Scalar operations. 
Fix problem Eli noticed where we were allowing pointer types to be splatted to
vector elements.
