Bug 1650702 - Use ARM's crypt extension for SHA1. r=kjacobs
ARM Crypto extension has SHA1 acceleration. Using this, SHA1 is 3 times
faster on ARMv8 CPU. The following data is AWS's a1 instance (Cortex-A72).
Before
======
```
# mode in opreps cxreps context op time(sec) thrgput
sha1_e 954Mb 31M 0 0.000 10000.000 10.000 95Mb
```
After
=====
```
# mode in opreps cxreps context op time(sec) thrgput
sha1_e 2Gb 94M 0 0.000 10000.000 10.000 288Mb
```
