For NGG GS, we need to store the following in LDS:
1. The ESGS ring, similarly to legacy ESGS.
2. Emitted vertices from the GS threads.
3. Temporary space used by the workgroup scan.

aco_instruction_selection_setup.cpp (previously used as a header) has
been split into a header and an implementation file. The latter "only"
implements init_context and setup_isel_context, but since these files
carry a long trail of helper functions, this cleans up the isel header
a lot.
Reduces library size by 3.1% due to more functions being compiled with
static linkage. Makes aco_instruction_selection.cpp compile 3% faster.

This information is exposed through shader->options->lower_int64_options.
Removing the extra arg forces drivers to initialize this field correctly.
This also allows us to check the int64 lowering options from each int64

This fixes a bunch of new robustness2 failures. Note that RADV/LLVM
