c3483a1823 CommonFuncs: Generify rotation functions and move them to BitUtils.h 
These are bit manipulation functions, so they belong within BitUtils.

This also gets rid of duplicated code and avoids relying on compiler
reserved names existing or not existing to determine whether or not we
define a set of functions.

Optimizers are smart enough in GCC and clang to transform the code to a
ROR or ROL instruction in the respective functions.

ffe085f5ea [AArch64] Implement CRC32 texture hashing. 
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.

1c388b6c37 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.

d2e004fa9e Use CRC to output 64 bits instead of 32 
A bit hacky, but should dramatically reduce the odds of hash collision.

4f02132f93 Make our architecture defines less stupid. 
Our defines were never clear between what meant 64bit or x86_64
This makes a clear cut between bitness and architecture.
This commit also has the side effect of bringing up aarch64 compiling support.
