Wrapper for os.makedirs that tolerates the directory already existing

Size routines.

Move n values starting at value i in this node into the values starting at value j in node x.

VK_USE_PLATFORM_SCREEN_QNX

VK_USE_PLATFORM_OHOS

VK_USE_PLATFORM_UBM_SEC

Used for things like Device Generated Commands which supply multiple stages (but all need to be in a single bind point)

Also disables shader caching and select shader instrumentation

This is used to help dump SPIR-V while debugging intermediate phases of any altercations to the SPIR-V

For spots we care if one pointer is null, or if both are not null, are the same values

Keeps only those bits in view_mask for which subpass is "enabled" based on subpass_per_view.

Because the following is legal, need the entry point OpEntryPoint GLCompute %main "name_a" OpEntryPoint GLCompute %main "name_b" Assumes shader module
