Pavel Labath f882f6fcd5 dotest.py: Remove useless AttributeError catches
Summary:
Test decorators were ignoring AttributeError exceptions. These were introduced three years ago,
and copied to all decorators. They seem to serve no purpose and removing them produces no errors.
Given that they have prevented us from noticing the problem in r249819, I am removing them.

James Molloy 55d633bd60 [LoopVectorize] Shrink integer operations into the smallest type possible
C semantics force sub-int-sized values (e.g. i8, i16) to be promoted to int
type (e.g. i32) whenever arithmetic is performed on them.

For targets with native i8 or i16 operations, usually InstCombine can shrink
the arithmetic type down again. However InstCombine refuses to create illegal
types, so for targets without i8 or i16 registers, the lengthening and
shrinking remains.

Most SIMD ISAs (e.g. NEON) however support vectors of i8 or i16 even when
their scalar equivalents do not, so during vectorization it is important to
remove these lengthens and truncates when deciding the profitability of
vectorization.

The algorithm this uses starts at truncs and icmps, trawling their use-def
chains until they terminate or instructions outside the loop are found (or
unsafe instructions like inttoptr casts are found). If the use-def chains
starting from different root instructions (truncs/icmps) meet, they are
unioned. The demanded bits of each node in the graph are ORed together to form
an overall mask of the demanded bits in the entire graph. The minimum bitwidth
that graph can be truncated to is the bitwidth minus the number of leading
zeroes in the overall mask.

The intention is that this algorithm should "first do no harm", so it will
never insert extra cast instructions. This is why the use-def graphs are
unioned, so that subgraphs with different minimum bitwidths do not need casts
inserted between them.

This algorithm works hard to reduce compile time impact. DemandedBits are only
queried if there are extends of illegal types and if a truncate to an illegal
type is seen. In the general case, this results in a simple linear scan of the
instructions in the loop.

No non-noise compile time impact was seen on a clang bootstrap build.

Andrea Di Biagio a0922ed8fe [x86] PR24562: fix incorrect folding of PSHUFB nodes with a mask where all indices have the most significant bit set.
This patch fixes a problem in function 'combineX86ShuffleChain' that causes a
chain of shuffles to be wrongly folded away when the combined shuffle mask has
only one element.

We may end up with a combined shuffle mask of one element as a result of
multiple calls to function 'canWidenShuffleElements()'.
Function canWidenShuffleElements attempts to simplify a shuffle mask by widening
the size of the elements being shuffled.
For every pair of shuffle indices, function canWidenShuffleElements checks if
indices refer to adjacent elements. If all pairs refer to "adjacent" elements
then the shuffle mask is safely widened. As a consequence of widening, we end up
with a new shuffle mask which is half the size of the original shuffle mask.

The byte shuffle (pshufb) from test pr24562.ll has a mask of all SM_SentinelZero
indices. Function canWidenShuffleElements would combine each pair of
SM_SentinelZero indices into a single SM_SentinelZero index. So, in a
logarithmic number of steps (4 in this case), the pshufb mask is simplified to
a mask with only one index which is equal to SM_SentinelZero.

Before this patch, function combineX86ShuffleChain wrongly assumed that a mask
of size one is always equivalent to an identity mask. So, the entire shuffle
chain was just folded away as the combined shuffle mask was treated as a no-op
mask.

With this patch we know check if the only element of a combined shuffle mask is
SM_SentinelZero. In case, we propagate a zero vector.

Abhishek Aggarwal b352a1c88f X86: Change FTAG register size in FXSAVE structure
Summary:
 - Changed from 16 bits to 8 bits for Intel Architecture
    -- FXSAVE structure now conforms with the layout of FXSAVE
       area specified by IA Architecture Software Developer Manual

 - Modified Linux and FreeBSD specific files to support this change
    -- MacOSX already uses 8 bits for ftag register

 - Modified TestRegisters.py and a.cpp:
    -- Change allows 8 bit comparison of ftag values

    -- Change resolves Bug 24733:
       Removed XFAIL for Clang as the test works and passes for
       Clang compiler as well

    -- Change provides a Generic/Better way of testing Bug 24457
       and Bug 25050 by using 'int3' inline assembly in inferior
