Bug 21328 – Forwarding static float array element inside a lambda crashes dmd backend

When upgrading to dmd 2.094 I found that this (reduced) code crashes dmd: ``` void bar(float x) {} void foo(float[1] arr) { () { bar(arr[0]); } (); } ``` It prints: tym = 0x227 [1] 14828 illegal hardware instruction dmd -c tymbug.d Suggesting a regression in dmd's backend. Possibly caused by: https://github.com/dlang/dmd/pull/11693 I have not verified this yet however.

Further reduced to: ``` void foo(float[1] arr) { () { float x = arr[0]; } (); } ``` The assert on src/dmd/backend/cgxmm.d:804 fails because `xmmstore` is called with tym_t = TYarray | mTYvolatile, and there is no case for TYarray in the `switch (tybasic(tym))`. I've bisected it with Digger, it's introduced in: https://github.com/dlang/dmd/pull/10200
