Propagate aliased lexical variables in byte compiler
Replace uses of a variable aliasing another variable with that aliased
variable, to allow for variable removal when possible. This also
enables opportunities for other optimisations. Example:
(let ((y x)) (f y)) => (f x)
The optimisation is only performed if both aliased and aliasing
variables are lexically bound. Shadowing bindings are α-renamed when
necessary for correctness. Example:
(let* ((b a) (a EXPR)) (f a b))

bug-reference-bug-regexp now defines a contract for the overlay region
Formerly, bug-reference-fontify placed the overlay on the complete
match of bug-reference-bug-regexp. That made it impossible to encode
constraints like "must not match at BOL" in the regexp without messing
up fontification. Therefore, now it establishes the contract that
subexpression 1 defines the overlay region. Subexpression 2 must
still match the part of the bug reference injected into
bug-reference-url-format if that's a string. If its a function, the
interpretation of subexpressions > 1 is up to the function.
For backwards compatibility, bug-reference-fontify checks if the
bounds of subexpression 2..10 are within the bounds of subexpession
1. If not, or subexpression 1 doesn't even exist/match, we fall back
to placing the overlay from (match-beginning 0) to (match-end 0) but
issue a warning.
