Reference to a static object within const fn leads to compiler panic.

[dark0ne]

I am initializing a reference to an object with static lifetime within a const function and the compiler panics.
I reduced the code to the following example:

https://play.rust-lang.org/?gist=2581bfb95f9f8e3f306bee0862f9f415&version=nightly&mode=debug

I get the compiler output:

error: internal compiler error: librustc_mir/monomorphize/collector.rs:1162: alloc id without corresponding allocation: 7

thread 'main' panicked at 'Box', librustc_errors/lib.rs:554:9
note: Run with RUST_BACKTRACE=1 for a backtrace.
error: aborting due to previous error

note: the compiler unexpectedly panicked. this is a bug.

note: rustc 1.27.0-nightly (565235e 2018-05-07) running on x86_64-unknown-linux-gnu

note: compiler flags: -C codegen-units=1 -C debuginfo=2 --crate-type bin

This is another symptom of #49955

You can work around it by using &(&FOO)[bar]
