Original commit message:
On "Unix", if Program::FindProgramByName is given a name containing
slashes, just go with it, regardless of whether it looks like it will
be executable. This follows the behavior of sh(1) more closely.
It's better when behaviour is consistent between platforms. This change also
makes FindExecutable() behave as expected on unix-likes (before this commit, it
used to always succeed).

- For now, loads of [r, r] addressing mode is the same as the

SelectionDAG shuffle nodes do not allow operands with different numbers of
...
elements than the result vector type. So, when an instruction like:
%8 = shufflevector <2 x float> %4, <2 x float> %7, <4 x i32> <i32 1, i32 0, i32 3, i32 2>
is translated to a DAG, each operand is changed to a concat_vectors node that appends 2 undef elements. That is:
shuffle [a,b], [c,d] is changed to:
shuffle [a,b,u,u], [c,d,u,u]
That's probably the right thing for x86 but for NEON, we'd much rather have:
shuffle [a,b,c,d], undef
