Merge #888

888: Added location data to Match Arm and removed unused code r=philberty a=mvvsmk

Fixes #863

- Added location data to Match arm in gcc/rust/ast/rust-expr.h and gcc/rust/hir/tree/rust-hir-expr.h
- Updated the respective constructors and copy constructors
- Updated location info for match arm in code generation in gcc/rust/backend/eust-compile-expr.cc
- Removed unused code in the above rust-expr.h and rust-gir-expr.h files as mentioned in the issue by `@philberty.`
- Comment removed form rust-expr.h
- Changed partameterized constructor and static function in
  rust-hir-expr.h
- Changed line 697 to pass expr.get_locus() in rust-ast-lower
- Changed parameterised constructor in rust-expr.h
- Changed line 8563 in rust-parse-impl.h to pass location data.

Note :
- I also added a public member funtion for the class MatchArm
`Location get_locus ( ) const { return locus; }`

Do me know if I missed anything or could improve on something.
