Nemanja Ivanovic e0407f5496 [PowerPC][Altivec] Fix offsets for vec_xl and vec_xst
As we currently have it implemented in altivec.h, the offsets for these two
intrinsics are element offsets. The documentation in the ABI (as well as the
implementation in both XL and GCC) states that these should be byte offsets.

Jinsong Ji 5309189d9b [PowerPC][Altivec] Fix constant argument for vec_dss
Summary:
This is similar to vec_ct* in https://reviews.llvm.org/rL304205.

The argument must be a constant, otherwise instruction selection
will fail. always_inline is not enough for isel to always fold
everything away at -O0.

The fix is to turn the function into macros in altivec.h.

Summary:
These all had somewhat custom file headers with different text from the
ones I searched for previously, and so I missed them. Thanks to Hal and
Kristina and others who prompted me to fix this, and sorry it took so

Nemanja Ivanovic 2447baff84 [PowerPC] Vector load/store builtins overstate alignment of pointers
A number of builtins in altivec.h load/store vectors from pointers to scalar
types. Currently they just cast the pointer to a vector pointer, but expressions
like that have the alignment of the target type. Of course, the input pointer
did not have that alignment so this triggers UBSan (and rightly so).

This resolves https://bugs.llvm.org/show_bug.cgi?id=39704

Zi Xuan Wu 71c35e13c3 [PowerPC] [Clang] [AltiVec] The second parameter of vec_sr function should be modulo the number of bits in the element
The second parameter of vec_sr function is representing shift bits and it should be modulo the number of bits in the element like what vec_sl does now. 
This is actually required by the ABI:

Each element of the result vector is the result of logically right shifting the corresponding
element of ARG1 by the number of bits specified by the value of the corresponding
element of ARG2, modulo the number of bits in the element. The bits that are shifted out
are replaced by zeros.

Tim Shen 867be0d14c [Altivec] Change vec_sl to a << (b % (sizeof(a) * 8))
For a << b (as original vec_sl does), if b >= sizeof(a) * 8, the
behavior is undefined. However, Power instructions do define the
behavior, which is equivalent to a << (b % (sizeof(a) * 8)).

This patch changes altivec.h to use a << (b % (sizeof(a) * 8)), to
ensure the consistent semantic of the instructions. Then it combines
the generated multiple instructions back to a single shift.

This patch handles left shift only. Right shift, on the other hand, is
more complicated, considering arithematic/logical right shift.

Ehsan Amiri 85f5bfcf0d [PPC] support for arithmetic builtins in the FE
(commit again after fixing the buildbot failures)

    vec_neg
    vec_nabs
    vec_adde
    vec_addec
    vec_sube
    vec_subec
    vec_subc

Note that for vec_sub builtins on 32 bit integers, the semantics is similar to
what ISA describes for instructions like vsubecuq that work on quadwords: the
first operand is added to the one's complement of the second operand. (As
opposed to two's complement which I expected).

Tony Jiang 6a49aad177 [PowerPC] Implement BE VSX load/store builtins - clang portion.
This patch implements all the overloads for vec_xl_be and vec_xst_be. On BE,
they behaves exactly the same with vec_xl and vec_xst, therefore they are
simply implemented by defining a matching macro. On LE, they are implemented
by defining new builtins and intrinsics. For int/float/long long/double, it
is just a load (lxvw4x/lxvd2x) or store(stxvw4x/stxvd2x). For char/char/short,
we also need some extra shuffling before or after call the builtins to get the
desired BE order. For int128, simply call vec_xl or vec_xst.

Removed the folowing interfaces either because their signatures have changed
in version 1.1 of the ABI or because they were implemented for ELF V2 ABI but
have actually been deprecated in version 1.1.

Bill Schmidt 8da737a18a [PPC64LE] Fix vec_sld semantics for little endian
The vec_sld interface provides access to the vsldoi instruction.
Unlike most of the vec_* interfaces, we do not attempt to change the
generated code for vec_sld based on the endian mode.  It is too
difficult to correctly infer the desired semantics because of
different element types, and the corrected instruction sequence is
expensive, involving loading a permute control vector and performing a
generalized permute.

For GCC, this was implemented as "Don't touch the vec_sld"
implementation.  When it came time for the LLVM implementation, I did
the same thing.  However, this was hasty and incorrect.  In LLVM's
version of altivec.h, vec_sld was previously defined in terms of the
vec_perm interface.  Because vec_perm semantics are adjusted for
little endian, this means that leaving vec_sld untouched causes it to
generate something different for LE than for BE.  Not good.

This patch adjusts the form of vec_perm that is used for vec_sld and
vec_vsldoi, effectively undoing the modifications so that the same
vsldoi instruction will be generated for both BE and LE.

There is an accompanying back-end patch to take care of some small
ripple effects caused by these changes.
