Matthew Winter d740b2b92d Lower indexing and selecting through a swizzle ...

Indexing a swizzle (`v.yx[i]`, `swizzle(v, ...)[i]`, `soa[i].zyx[j]`) or
taking a selector of one (`v.zyx.x`, `v.zyx.xy`) asked for the swizzle's
pointer, which `lb_addr_get_ptr` panics on, crashing the compiler.

An index now reads from a copy of the swizzle, as the checker never lets
it be assigned. A selector maps its components onto the swizzled
variable, so assigning through it still writes to that variable.

Fixes #7889
