libgo: build with -Wa,-nH if possible on Solaris
By default the Solaris assembler records the required hardware
capability in the object file. This means that the AES hashing code
breaks on systems that do not support AES, even though the code uses a
runtime check to only actually invoke the AES instructions on systems
that support it. An earlier fix for the problem only fixed the shared
library, not the static libgo.a. Fix the problem for real by using an
assembler option to not record the hardware capability.
For GCC PR 78978.

simplify_transformation_to_array had the nested loop unrolled 7 times,
which is reasonable given that it iterates over arrays of size
GFC_MAX_DIMENSIONS == 7.
The problem is that the last iteration increments the index, tests
that it's less than result->rank, and then accesses the arrays with
the incremented index.
We did not optimize out that part in the 7th iteration, so VRP flagged
the unreachable code as accessing arrays past the end.
It couldn't possibly know that we'd never reach that part, since the
test was on result->rank, and it's not obvious (for the compiler) that
result->rank <= GFC_MAX_DIMENSIONS.
Even an assert to that effect before the enclosing loop didn't avoid
the warning turned to error, though; I suppose there might be some
aliasing at play, because moving the assert into the loop does. An
assert on the index itself would also work, even more efficiently, but
we're just silencing the warning instead.
