Change TerminatorKind::Abort to call the panic handler instead of
...
aborting immediately.
The panic handler is called with a special flag which forces it to abort
after calling the panic hook.

within libcore.

Deduplicate panic_fmt
...
std's begin_panic_fmt and core's panic_fmt are duplicates.
Merge them to declutter code and remove a lang item.

Use ZST for fmt unsafety
...
This allows the format_args! macro to keep the pre-expansion code out of
the unsafe block without doing gymnastics with nested `match`
expressions. This reduces codegen.

Make const panic!("..") work in Rust 2021.
...
During const eval, this replaces calls to core::panicking::panic_fmt and
std::panicking::being_panic_fmt with a call to a new const fn:
core::panicking::const_panic_fmt. That function uses
fmt::Arguments::as_str() to get the str and calls panic_str with that
instead.
panic!() invocations with formatting arguments are still not accepted,
as the creation of such a fmt::Arguments cannot be done in constant
functions right now.
