Implement ad hoc regex pattern rule support
An ad hoc pattern rule consists of a pattern that mimics a dependency declaration followed by one or more recipes. For example: exe{~'/(.*)/'}: cxx{~'/\1/'} {{ $cxx.path -o $path($>) $path($<[0]) }} If a pattern matches a dependency declaration of a target, then the recipe is used to perform the corresponding operation on this target. For example, the following dependency declaration matches the above pattern which means the rule's recipe will be used to update this target: exe{hello}: cxx{hello} While the following declarations do not match the above pattern: exe{hello}: c{hello} # Type mismatch. exe{hello}: cxx{howdy} # Name mismatch. On the left hand side of `:` in the pattern we can have a single target or an ad hoc target group. The single target or the first (primary) ad hoc group member must be a regex pattern (~). The rest of the ad hoc group members can be patterns or substitutions (^). For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} On the left hand side of `:` in the pattern we have prerequisites which can be patterns, substitutions, or non-patterns. For example: <exe{~'/(.*)/'} file{^'/\1.map/'}>: cxx{~'/\1/'} hxx{^'/\1/'} hxx{common} {{ $cxx.path -o $path($>[0]) "-Wl,-Map=$path($>[1])" $path($<[0]) }} Substitutions on the left hand side of `:` and substitutions and non-patterns on the right hand side are added to the dependency declaration. For example, given the above rule and dependency declaration, the effective dependency is going to be: <exe{hello} file{hello.map>: cxx{hello} hxx{hello} hxx{common}
