LLVM backend panic when comparing array of strings with empty string literal

[FourteenBrush]

Context

Odin:    dev-2025-02
OS:      NixOS 25.05 (Warbler), Linux 6.6.71
CPU:     AMD Ryzen 7 5800H with Radeon Graphics         
RAM:     15847 MiB
Backend: LLVM 18.1.8

Current Behavior

package test

main :: proc() {
    x: [4]string
    if x == "" {}
}

src/llvm_backend_expr.cpp(3195): Panic: Unknown handled type: [4]string -> [4]string

This does not happen when using anything else than an empty string literal

Failure Information (for bugs)

Relevant gdb output:

src/llvm_backend_expr.cpp(3195): Panic: Unknown handled type: [4]string -> [4]string

Thread 13 ".odin-wrapped" received signal SIGILL, Illegal instruction.
[Switching to Thread 0x7fffe86a56c0 (LWP 759814)]
0x000055555570489e in lb_emit_comp_against_nil(lbProcedure*, TokenKind, lbValue) ()
(gdb) 

Steps to Reproduce

Use the above code, and attempt to build it with odin build main.odin -file
