a04e649c09 Auto merge of #114028 - Centri3:ternary-operator, r=compiler-errors 
Gracefully handle ternary operator

Fixes #112578

~~May not be the best way to do this as it doesn't check for a single `:`, so it could perhaps appear even when the actual issue is just a missing semicolon. May not be the biggest deal, though?~~

Nevermind, got it working properly now ^^

My type ascription
Oh rip it out
Ah
If you think we live too much then
You can sacrifice diagnostics
Don't mix your garbage
Into my syntax
So many weird hacks keep diagnostics alive
Yet I don't even step outside
So many bad diagnostics keep tyasc alive
Yet tyasc doesn't even bother to survive!

d1fcf61117 errors: generate typed identifiers in each crate 
Instead of loading the Fluent resources for every crate in
`rustc_error_messages`, each crate generates typed identifiers for its
own diagnostics and creates a static which are pulled together in the
`rustc_driver` crate and provided to the diagnostic emitter.

Add suggestion to remove if in let...else block 
Adds an additional hint to failures where we encounter an else keyword
while we're parsing an if-let block.

This is likely that the user has accidentally mixed if-let and let...else
together.

358a603f11 Use token::Lit in ast::ExprKind::Lit. 
Instead of `ast::Lit`.

Literal lowering now happens at two different times. Expression literals
are lowered when HIR is crated. Attribute literals are lowered during
parsing.

This commit changes the language very slightly. Some programs that used
to not compile now will compile. This is because some invalid literals
that are removed by `cfg` or attribute macros will no longer trigger
errors. See this comment for more details:
