Cool. I'm investigating the split_reduceop bounty as my primary focus right now (not ready for a draft PR yet), but I'll work on this test migration in batches sporadically, if...

test_linearizer has > 20 tests that use LazyOp. to keep each PR reasonably sized, I'm thinking of breaking the port of this file into smaller batches. However, if its preferable...

@Qazalin regarding > Should also fix DEFINE_ACC's extra type_verify assert. I was looking at [you convo with geohot regarding this](https://discord.com/channels/1068976834382925865/1068982781490757652/1254860202566488165 ) but I wasn't able to come to a firm...

I'm diff'ing process replay runs + ASSERT_PROCESS_REPLAY=0 with and without commit 61f9453 and I'm seeing different kernels getting generated. So looks like I've got more work to do.

Note: I added the GEP-VECTORIZE-CONST rule because I was getting some strange UOps sequences without it after updating UOps.const(). Attaching GRAPHUOPS=1 images with (gg.uops.svg) and without the rule (bg.uops.svg) --...

> @greg-niemeyer when I was playing around with the code, when rendering DEFINE_ACC, it calls render_const with vectorized dtypes sometimes. That might be part of the assert fail. right, I'm...

Had to add [the render_cast for !(int, bool, float)](https://github.com/tinygrad/tinygrad/pull/5322/commits/499f7e85ab764e90dd7a000ce5ed0b7d14393c52) back -- there are longs, shorts, etc. that need their long-form cast rendered.

I'm not super happy with [DEFINE_ACC implicitly vectorizing CONST in cstyle](https://github.com/tinygrad/tinygrad/pull/5322/files#diff-9694d15708a36a57a7e1485db60b1b4b1d2fc1e7278bc87127a73efd0bfa7dc0R171-R173). Should I update DEFINE_ACC in UOps such that its src is VECTORIZE or CONST, consistent with its dtype?
