This patch introduces multiplicative cost scaling (x2/x4/x8) to model
the higher latency and register pressure of larger LMULs. The scaling
is applied uniformly in adjust_stmt_cost for all vector operations.
In addition to VLA, VLS should also get the same LMUL cost scaling,
but doing so causes too many testsuite regressions currently,
mostly because these tests also need expectation updates.
This is left for future work.
All failures displayed in CI should have been fixed. Changes here are
all expectation updates, except for slp_run-17.c which is pre-existing
— I will open a PR for it later.
OK, thanks.
And I've pushed it to the trunk. Thanks!
