As a part of safety check, golden context is created twice
(back to back) and two golden context images are compared.
These two images should be identical for safety check.
Currently there is one hw deviation happening because of stats
counter idle clock increments. To avoid this, stats counter
clocks enable is disabled. To have a valid golden context(
avoid mismatch between fe and mpc), original stats counter
bundle is programmed through mme shadow register.
Before first golden context save, golden image is saved in
a local copy. Same copy is restored back after first golden
save. Second golden context save is done with this local copy
and two golden contexts are compared.

struct nvgpu_gr_global_ctx_local_golden_image *local_golden_image1,

In case of sysmmem, direct mem comparison can be used and for vidmem.
only word by word comparison can be done.
Since this code is used only for safety, all implementation is under
NV_BUILD_CONFIGURATION_IS_SAFETY flag.

Shortcomings of ALIGN macros:
- ALIGN_MASK down aligns when there is an wrapping/overflow instead of
throwing an error. This can affect the size assumptions.
- Alignment a's check will be bypassed when ALIGN_MASK is directly
used.
Fix these issues by 1) adding compile time error for non-unsigned type
arguments 2) using unsigned type safe ops for addition and subtraction.
Also, change users of ALIGN to pass unsigned types only.

For posix, we assert() and die if pthread_mutex_init fails.
