Types defined within a __builtin_offsetof argument don't always get
properly recorded as members of their context types, so if they're
anonymous, we may fail to assign them an anon type index for mangling
and ICE.

We shouldn't allow types to be introduced in __builtin_offsetof, I
think, and Jason says the std committee agrees, so I've arranged for
us to reject them.

Even then, we still parse the definitions and attempt to assign
mangled names to its member functions, so the ICE remains.  Since
we've already reported an error, we might as well complete the name
assignment with an arbitrary index, thus avoiding the ICE.

We used to have a test that expected to be able to define types in
__builtin_offsetof; this patch removes that specific test.

The -mno-direct-move option causes a lot of problems, since it forces
us to be able to generate code for p8 and up with some crucial
instructions missing.  This patch removes the -m[no-]direct-move
options so that the user cannot put us into this unexpected situation
anymore.  Internally we still have all the same flags, and they are
automatically set based on -mcpu; getting rid of that is a lot more
work and will have to wait for GCC 9 (in some places the flag is used
to see if we are compiling for a p8 _at all_).

The powerpc versions of _mm_slli_epi32 and __mm_slli_epi64 in emmintrin.h
do not properly handle shift values between 16 and 31, inclusive.
These are setting up the shift with vec_splat_s32, which only accepts
*5 bit signed* shift values, or a range of -16 to 15.  Values above 15
produce an error:

  error: argument 1 must be a 5-bit signed literal

Fix is to effectively reduce the range for which vec_splat_s32 is used
to < 32 and use vec_splats otherwise.

Also, __mm_slli_epi{16,32,64}, when given a negative shift value,
should always return a vector of {0}.


	PR target/83402
	* config/rs6000/emmintrin.h (_mm_slli_epi{16,32,64}):
	Ensure that vec_splat_s32 is only called with 0 <= shift < 16.
	Ensure negative shifts result in {0}.

PR c++/85385 reports an issue where we emit bogus "macro had not yet been
defined" notes when a macro is mis-used:

  $ cat test.c
  #define MACRO(X,Y)

  void test ()
  {
    MACRO(42);
  }

  $ ./xg++ -B. -c test.c
  test.c:5:11: error: macro "MACRO" requires 2 arguments, but only 1 given
     MACRO(42);
             ^
  test.c: In function ‘void test()’:
  test.c:5:3: error: ‘MACRO’ was not declared in this scope
     MACRO(42);
     ^~~~~
  test.c:5:3: note:
  test.c:1: note: it was later defined here
   #define MACRO(X,Y)

The macro *had* been defined, it was merely misused.

This patch fixes the issue by only issuing the note if the use location
is before the definition location (using linemap_location_before_p).

	PR c++/85385
