<pre>The following test case crashes:
define void @test5(i28 %arg) gc "statepoint-example" {
%safepoint_token = call token (i64, i32, void ()*, i32, i32, ...)
@llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()*
@do_safepoint, i32 0, i32 0, i32 0, i32 2, i128 %arg, i128 0)
ret void
}
This is exercising two different cases of trying to encode a 128 bit integer
into the stackmap. The argument appears to cause a legalization bug. The i128
bit constant works, but only because the actual constant is encodable in 64
bits. A 10..62..0 constant would not be.</pre>
