perlasm/ppc-xlate.pl: Fix build on OS X

vsr2vr1() fails on OS X because the main loop doesn't strip the
non-numeric register prefixes for OS X.

Strip any non-numeric prefix (likely just "v") from registers before
doing numeric calculation, then put the prefix back on the result.

Add aix64-gcc-as architecture and p2align callback

This commit adds an architecture named aix64-gcc-as which can generate
assembler source code compatible with AIX assembler (as) instead of the
GNU Assembler (gas). This architecture name is then used in a callback
for the .p2align directive which is not available in AIX as.

The motivation for this addition came out of an issue we ran into when
working on upgrading OpenSSL in Node.js. We ran into the following
compilation error on one of the CI machines that uses AIX:

05:39:05 Assembler:
05:39:05 crypto/bn/ppc64-mont-fixed.s: line 4: Error In Syntax

This machine is using AIX Version 7.2 and does not have gas installed
and the .p2align directive is causing this error. After asking around if
it would be possible to install GAS on this machine I learned that AIX
GNU utils are not maintained as well as the native AIX ones and we
(Red Hat/IBM) have run into issues with the GNU utils in the past and if
possible it would be preferable to be able to use the AIX native
assembler.

perlasm/ppc-xlate.pl: Handle rewriting of vector registers

Power has 2 numbering systems for vector registers:

* VR: Vector Registers are numbered from 0 to 31
* VSR: Vector-Scalar registers are numbers from 32 to 63

These refer to the same registers. Some instructions use VR numbering
for their operands, while others use VSR numbering.

When using Perl to provide a meaningful name for a register it makes
sense to use the same variable for both VR and VSR instructions. This
makes the code more readable.

However, providing a VSR number (i.e. >=32) to an instruction that
expects a VR number will cause an assembler error.

So, for instructions that require VR numbering, map VSR numbers
(i.e. >=32) to VR numbers. This also allows existing code that uses
VR numbering to remain unchanged.

In https://github.com/openssl/openssl/pull/10883, I'd meant to exclude
the perlasm drivers since they aren't opening pipes and do not
particularly need it, but I only noticed x86_64-xlate.pl, so
arm-xlate.pl and ppc-xlate.pl got the change.

That seems to have been fine, so be consistent and also apply the change
to x86_64-xlate.pl. Checking for errors is generally a good idea.

Do not silently truncate files on perlasm errors

If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).

Remove trailing whitespace from some files.

The prevailing style seems to not have trailing whitespace, but a few
lines do. This is mostly in the perlasm files, but a few C files got
them after the reformat. This is the result of:

find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'

Then bn_prime.h was excluded since this is a generated file.

Note mkerr.pl has some changes in a heredoc for some help output, but
other lines there lack trailing whitespace too.
