Allow binding of nested patterns
...
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is
boundvar@subpattern
Which will match the subpattern as usual, but also bind boundvar to the
whole matched value.
Closes #838

Allow literal patterns to contain arbitrary literal expressions
...
This removes the need for the unary minus hacks, and allows some other
neat things like matching on 1 >> 4.

Move functions from syntax::ast to syntax::ast_util

Implement pattern guards

The syntax is
alt x {
mypat where mycond { ... }

The condition may refer to any of the variables bound by the pattern.
When a guard fails, pattern-matching continues with the next pattern.
