81edc9beb6 Do away with BN_LLONG in favor of BN_ULLONG.
BN_LLONG is only ever used in #ifdefs. The actual type is BN_ULLONG. Switch the
ifdefs to check on BN_ULLONG and remove BN_LLONG. Also fix signedness of all
the constants (potentially avoiding undefined behavior in some operations).

9361243065 Don't include <alloca.h>, it's no longer needed.
Relevant code was removed in 5d5e39f5d2.

5d5e39f5d2 Remove non-ASM version of |bn_mul_mont| in bn/generic.c.
When building in OPENSSL_NO_ASM mode, MSVC complains about unreachable
code. The redundant initialization of |i| is the main problem. The
skipping of the first test of the condition |i < num| with |goto| was
also confusing.

It turns out that |bn_mul_mont| is only called when assembly language
optimizations are available, but in that case the assmebly language
versions will always be used instead. Although this code will be
compiled in |OPENSSL_NO_ASM| builds, it is never called in
|OPENSSL_NO_ASM| builds. Thus, it can just be removed.

7bd538d94d Remove an unreachable expression.
The goto always jumps into the loop so the for's initialisation
expression can never be executed. Clang warns about this.

3e6526575a aarch64 support.
This is an initial cut at aarch64 support. I have only qemu to test it
however—hopefully hardware will be coming soon.

This also affects 32-bit ARM in that aarch64 chips can run 32-bit code
and we would like to be able to take advantage of the crypto operations
even in 32-bit mode. AES and GHASH should Just Work in this case: the
-armx.pl files can be built for either 32- or 64-bit mode based on the
flavour argument given to the Perl script.

SHA-1 and SHA-256 don't work like this however because they've never
support for multiple implementations, thus BoringSSL built for 32-bit
won't use the SHA instructions on an aarch64 chip.

No dedicated ChaCha20 or Poly1305 support yet.

f44aa68a26 Fix standalone Win64 build.
generic.c still needs to include generic implementations in Win64.
Those are currently done with inline assembly and won't work on
MSVC.

3e700bb3e8 Get MASM output working on Win32.
We were building the NASM flavor with MASM which is why it didn't work. Get the
MASM output working: cpuid and cmove are not available in MASM unless the file
declares .686. Also work around MASM rejecting a very long line in SHA-256.

The follow-up change will get the NASM flavor working. We should probably use
that one as it's documented as supported upstream. But let's make this one
functional too.
