The s390x assembly for shlVU does a forward copy when the shift amount s
is 0. This causes corruption of the result z when z is aliased to the
input x.
This fix removes the s390x assembly for both shlVU and shrVU so the pure
go implementations will be used.
Test cases have been added to the existing TestShiftOverlap test to
cover shift values of 0, 1 and (_W - 1).
Fixes #45335

For the case where the addresses of parameter z and x of the function
shlVU overlap and the address of z is greater than x, x (input value)
can be polluted during the calculation when the high words of x are
overlapped with the low words of z (output value).

The biggest hot spot of the existing implementation is "load" operations, which lead to poor performance.
By unrolling the cycle 4 times and 2 times, and using "LDP", "STP" instructions,
this CL can reduce the "load" cost and improve performance.

The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.
This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:

(platforms w/o corresponding assembly kernels)
For short vector adds there's some erradic slow-down, but overall
these routines have become significantly faster. This only matters
for platforms w/o native (assembly) versions of these kernels, so
we are not concerned about the minor slow-down for short vectors.
This code was already reviewed under Mercurial (golang.org/cl/172810043)
but wasn't submitted before the switch to git.
Benchmarks run on 2.3GHz Intel Core i7, running OS X 10.9.5,
with the respective AddVV and AddVW assembly routines disabled.
