The failures look like they might be related? |

Taking a look... Edit: the bug has been identified and fixed. |
Good on me for noticing it a few weeks ago in dotnet#79722... ``` // Otherwise, must be local lhs form. TODO-Bug: this doesn't account for LCL_FLD. // This will miss memory havoc induced by address-exposed local field stores. ```

The two changes help to fix the CQ gap that exists today between
LCL_FLDandIND(LCL_ADDR)forms of access to address-exposed locals.Positive diffs, with some regressions due to the usual reasons associated with more CSEing (e. g. the large x86 test regressions are actually PerfScore improvements). A bit of a TP regression due to more VNing, will be payed for with #79722.
