fcccd9f4ec Improve BitLocker -m 22100 performance by: 
- Removing OPTI_TYPE_REGISTER_LIMIT
- Removing OPTS_TYPE_MP_MULTI_DISABLE
- Enabling REAL_SHM
- Fixing loop value to allow autotune to find better accel value
- Increasing minimum password length from 4 to 6
Fix compiler warning
Rename HASH_NAME for -m 31100

e6ed9f5050 Revert to manually unrolled SHA256/224/512/384 transform() steps 
This affects the inner core of nearly all kernels and thus impacts
almost all hash modes. The only functional change is that we now
manually unroll the individual steps of the transform() functions,
saving a small amount of constant memory.

In most cases, JIT compilers would likely detect the unused constant
buffer and remove it automatically, but this makes it explicit.

Tested on newer NVIDIA devices: no speed change observed.
Tested on older NVIDIA devices: visible speed increase.
Tested on AMD devices: visible speed increase across all tested GPUs.

Not yet tested: CPUs, Intel iGPUs, Intel dGPUs.

b7dffd9259 Improve performance for UTF8->UTF16 conversion 
Reverted d343e2c4a0 and ee26805138
Adds a test to decide whatever conversion technique to use. If all UTF8 characters are 7 bit, there's no need for regular conversion and we can stick to naive conversion.
