0a3663a64f ARMv4 assembly pack: harmonize Thumb-ification of iOS build.
Three modules were left behind in
I59df0b567e8e80befe5c399f817d6410ddafc577.

(Imported from upstream's c93f06c12f10c07cea935abd78a07a037e27f155.)

This actually meant functions defined in those two files were
non-functional. I'm guessing no one noticed upstream because, if you go
strictly by iOS compile-time capabilities, all this code is unreachable
on ios32, only ios64.

ae96383af3 ARMv4 assembly pack: implement support for Thumb2.
As some of ARM processors, more specifically Cortex-Mx series, are
Thumb2-only, we need to support Thumb2-only builds even in assembly.

c07635f869 Remove local __arm__ ifdef on aes-armv4.pl.
We patch arm-xlate.pl to add the ifdefs, so this isn't needed and
reduces our upstream diff.

(We do still have a diff from upstream here. Will go through them
shortly.)

7c075b99e2 Change ppc64le AES code for FIPS.
The symbol “rcon” should be local in order to avoid collisions and it's
much easier on delocate if some of the expressions are evalulated in
Perl rather than left in the resulting .S file.

Also fix the perlasm style so the symbols are actually local.

3ecd0a5fca Convert aes_test to GTest.
This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:

- It returns void and expects failures to use the GTest EXPECT_* and
  ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
  work to convert, but ultimately less work to add new tests. I think
  it's also valuable for our FileTest and normal test patterns to align
  as much as possible. The line number is emitted via SCOPED_TRACE.

- I've intentionally omitted the Error attribute handling, since that
  doesn't work very well with the new callback. This means evp_test.cc
  will take a little more work to convert, but this is again to keep our
  two test patterns aligned.

- The callback takes a std::function rather than a C-style void pointer.
  This means we can go nuts with lambdas. It also places the path first
  so clang-format doesn't go nuts.

BUG=129

def85b403d Revise OPENSSL_ia32cap_P strategy to avoid TEXTRELs.
OPENSSL_ia32cap_addr avoids any relocations within the module, at the
cost of a runtime TEXTREL, which causes problems in some cases.
(Notably, if someone links us into a binary which uses the GCC "ifunc"
attribute, the loader crashes.)

We add a OPENSSL_ia32cap_addr_delta symbol (which is reachable
relocation-free from the module) stores the difference between
OPENSSL_ia32cap_P and its own address.  Next, reference
OPENSSL_ia32cap_P in code as usual, but always doing LEAQ (or the
equivalent GOTPCREL MOVQ) into a register first. This pattern we can
then transform into a LEAQ and ADDQ on OPENSSL_ia32cap_addr_delta.

ADDQ modifies the FLAGS register, so this is only a safe transformation
if we safe and restore flags first. That, in turn, is only a safe
transformation if code always uses %rsp as a stack pointer (specifically
everything below the stack must be fair game for scribbling over). Linux
delivers signals on %rsp, so this should already be an ABI requirement.
Further, we must clear the red zone (using LEAQ to avoid touching FLAGS)
which signal handlers may not scribble over.

This also fixes the GOTTPOFF logic to clear the red zone.

0648129566 Move modes/ into the FIPS module
The changes to delocate.go are needed because modes/ does things like
return the address of a module function. Both of these need to be
changed from referencing the GOT to using local symbols.

Rather than testing whether |ghash| is |gcm_ghash_avx|, we can just keep
that information in a flag.

The test for |aesni_ctr32_encrypt_blocks| is more problematic, but I
believe that it's superfluous and can be dropped: if you passed in a
stream function that was semantically different from
|aesni_ctr32_encrypt_blocks| you would already have a bug because
|CRYPTO_gcm128_[en|de]crypt_ctr32| will handle a block at the end
themselves, and assume a big-endian, 32-bit counter anyway.
