Adam Langley b2fa06b6af blake2s: fix build constraints
Having a trailing comma before a space doesn't mean that the next option
will be ANDed rather than ORed. This worked with the standard toolchain
because the filenames prevented the incorrect build constraints for
other platforms from being acted on.

Austin Clements 814723eff7 blake2s: test all four hashing implementations
This adds use* flags for all arches so a common test can observe what
implementations are supported and test all supported implementations.

Austin Clements 3c0d69f177 blake2s: fix frame size of hashBlocksSSE4
The frame is actually 16 bytes plus alignment, not 0.

This fixes the build on Go 1.6.

Austin Clements a9ecc67d46 blake2s: remove NOSPLIT from asm functions
Now that the frame sizes of these functions are correct, the compiler
is detecting that they overflow the NOSPLIT stack. They don't need to
be NOSPLIT, so remove that flag.

This fixes the 1.7 build. The build is not broken at tip because the
stack guard is larger.

Austin Clements 5953a478da blake2s: use proper Go frame sizes
Currently blake2s's assembly routines claim they have a zero byte
frame and manually subtract upwards of 704 bytes from the stack
pointer without cooperating with Go's ABI. As a result, these
functions may not grow the stack when necessary, leading to memory
corruption.

Fix this by using the correct stack frame sizes so the generated stack
growth prologue is correct, and aligning the SP up instead of down.
