[AArch64] Implement CRC32 texture hashing.

2015-06-09T00:16:50+00:00

In a particular hashing heavy scene in Crazy Taxi the Murmur3 hash used 3.11% CPU time.
The new CRC32 hash in the same scene used 1.86%
This was tested on a Nvidia SHIELD Android TV with Cortex-A57s.

This will be a bit slower on the Nexus 9, the Denver CPU core is a bit slower with CRC32 texture hashing than Murmur3 texture hashing.

Fix clang on x86_64.

If we are compiling in the CRC32 hash, clang has an issue with casting a s32 to a u64.
Change our lens argument to a unsigned integer to fix the issue.

VideoCommon: make hash independet from hires textures

Use CRC to output 64 bits instead of 32

A bit hacky, but should dramatically reduce the odds of hash collision.

Hash: unroll CRC loop, since CRC32 typically has nontrivial latency

Seems to be about 20-30% faster texture cache hashing on my machine.
