Commit Message

codegen: Allow a non-constant zeroing flag on `julia.gc_alloc_memory` (#64250)

LLVM can merge two `julia.gc_alloc_memory` calls for Memory types that differ
in whether their data must be zeroed, for example after union-splitting
`collect`, which turns the zeroing flag into a phi. LateLowerGCFrame cast the
flag to a constant, which tripped an assertion and crashed release builds
during compilation, for example in the tests of Tables.jl and CSV.jl.

Zero the data conditionally when the flag is not a constant.

Assisted-by: Claude Code (Opus 5.5)
