1206: Use correct format specifiers for unisnged HOST_WIDE_INT r=philberty a=philberty

The code here was wrongly assuming the unsigned long interface which is not
correctly for all targets.


1209: Allow match on boolean expressions r=philberty a=dafaust

Enables compiling `match` expressions where the scrutinee is a boolean expression. Also enable compiling match arms with Literal patterns, since `true` and `false` literals are commonly used with matches on boolean expressions.

Fixes: #1207 

1211: Preserve inside_loop context when type checking match r=philberty a=dafaust

Previously, we would lose the context of being inside a loop when compiling a `match`.
This would lead to incorrect error messages like "cannot 'break' outside of a loop" when
trying to break out of a loop from within a `match` expression.

Fixes: #1196
