Memory pressure
- parfors test cannot finish within 60minutes limit on CI
- parfors test is compiling to isolated context
  - caching compilation helps memory use (up to 4x)
- @overload is making unnecessary cpython and cfunc wrappers
  - fixing this has minor effect to memory use

#7159 - CUDA regression: Mixing debug kwargs between called functions results in linkage error
#7158 - objmode error in IR legalization
- Fix is to split the legalization pass
- Should be easy enough to fix during RC
#7155 - Parfors max_label issue causing undefined behavior
#7153 - CUDA: NVVM segfault when indexing in a loop with a zip
#7151 - Refactor: extract common logic of target registry selection
#7150 - Refactor: make helper function for selecting/sorting target-specific template
#7148 - Using TBB with numba fails with pip install, works with apt install
*** #7135 access to namedtuple
- It would be preferable if this actually generated a stacktrace or error

#7157 - [DO NOT MERGE] CI Testing
- we need a proper fix for this, current ideas revolve around removing compiler flags and splitting the parfors tests into their own test cases to reduce the testing overhead
#7156 - Fix ir_utils._max_label being updated incorrectly
#7154 - adding experimental change-log for 0.54.0dev0
