- request for improvement for faster key setup in RT#3576;
- clearing registers and stack in RT#3554 (this is more of a gesture to
see if there will be some traction from compiler side);
- more commentary around input parameters handling and stack layout
(desired when RT#3553 was reviewed);
- minor size and single block performance optimization (was lying around);

This facilitates "universal" builds, ones that target multiple

(Imported from upstream's c1669e1c205dc8e695fb0c10a655f434e758b9f7)
This is a change from a while ago which was a source of divergence between our
perlasm and upstream's. This change in upstream came with the following comment
in Configure:
Note that -march is not among compiler options in below linux-armv4
target line. Not specifying one is intentional to give you choice to:
a) rely on your compiler default by not specifying one;
b) specify your target platform explicitly for optimal performance,
e.g. -march=armv6 or -march=armv7-a;
c) build "universal" binary that targets *range* of platforms by
specifying minimum and maximum supported architecture;
As for c) option. It actually makes no sense to specify maximum to be
less than ARMv7, because it's the least requirement for run-time
switch between platform-specific code paths. And without run-time
switch performance would be equivalent to one for minimum. Secondly,
there are some natural limitations that you'd have to accept and
respect. Most notably you can *not* build "universal" binary for
big-endian platform. This is because ARMv7 processor always picks
instructions in little-endian order. Another similar limitation is
that -mthumb can't "cross" -march=armv6t2 boundary, because that's
where it became Thumb-2. Well, this limitation is a bit artificial,
because it's not really impossible, but it's deemed too tricky to
support. And of course you have to be sure that your binutils are
actually up to the task of handling maximum target platform.

kinda dumb for a client to do this, but apparently the spec allows this.
Judging by code inspection, OpenSSL 1.0.1 also allowed this, so this avoids a
behavior change when switching from 1.0.1 to BoringSSL.
Add a test for this, which revealed that, unlike upstream's version, this
actually works with ecdh_auto since tls1_get_shared_curve also needs updating.

The 2 arg OpenSSL sk_find() returned -1 on error and >= 0 on

In practice, all callers of the sk_find() macros in BoringSSL only
check for zero/non-zero. If sk is ever NULL, it looks like most
callers are going to use uninitialized data as the index because
the return value check is insufficient.
