Eric Christopher 758aad76d8 Remove the -faltivec alias option and replace it with -maltivec everywhere. 
The alias was only ever used on darwin and had some issues there,
and isn't used in practice much. Also fixes a problem with -mno-altivec
not turning off -maltivec.

Also add a diagnostic for faltivec/fno-altivec that directs users to use
maltivec options and include the altivec.h file explicitly.

Bill Schmidt 1cf7c64fa5 [PPC64LE] Run some existing Altivec tests on powerpc64le as well 
There are several Altivec tests that formerly ran only on big-endian
targets (and in some cases only on 32-bit targets).  It is useful to
verify these on little-endian targets as well.

While testing these, I discovered a typo in <altivec.h>.  This is also
fixed by this patch.

Chandler Carruth b653131345 Move a bunch of tests to directly use the CC1 layer. This at least saves 
a subprocess invocation which is pretty significant on Windows. It also
likely saves a bunch of thrashing the host machine needlessly. Finally
it makes the tests much more predictable and less dependent on the host.
For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to
thwart the host detection adding it into the compilation. By runnig CC1
directly we don't have to deal with such oddities.

Bill Schmidt 99a084b7ae "bool" should be a context-sensitive keyword in Altivec mode. 
PR16456 reported that Clang implements a hybrid between AltiVec's
"Keyword and Predefine Method" and its "Context Sensitive Keyword
Method," where "bool" is always a keyword, but "vector" and "pixel"
are context-sensitive keywords.  This isn't permitted by the AltiVec
spec.  For consistency with gcc, this patch implements the Context
Sensitive Keyword Method for bool, and stops treating true and false
as keywords in Altivec mode.

The patch removes KEYALTIVEC as a trigger for defining these keywords
in include/clang/Basic/TokenKinds.def, and adds logic for "vector
bool" that mirrors the existing logic for "vector pixel."  The test
case is taken from the bug report.
