gccrs: add support for lang_item eq and PartialEq trait
The Eq and Partial Ord are very similar to the operator overloads
we support for add/sub/etc... but they differ in that usually the
function call name matches the name of the lang item. This time
we need to have support to send in a new path for the method call
on the lang item we want instead of just the name of the lang item.
NOTE: this test case doesnt work correctly yet we need to support
the derive of partial eq on enums to generate the correct comparison
code for that.
Fixes Rust-GCC#3302
gcc/rust/ChangeLog:
* backend/rust-compile-expr.cc (CompileExpr::visit): handle partial_eq possible call
* backend/rust-compile-expr.h: handle case where lang item calls differ from name
* hir/tree/rust-hir-expr.cc (OperatorExprMeta::OperatorExprMeta): new helper
* hir/tree/rust-hir-expr.h: likewise
* typecheck/rust-hir-type-check-expr.cc (TypeCheckExpr::visit): handle partial_eq
(TypeCheckExpr::resolve_operator_overload): likewise
* typecheck/rust-hir-type-check-expr.h: likewise
* util/rust-lang-item.cc (LangItem::ComparisonToLangItem): map comparison to lang item
(LangItem::ComparisonToSegment): likewise
* util/rust-lang-item.h: new lang items PartialOrd and Eq
* util/rust-operators.h (enum class): likewise
gcc/testsuite/ChangeLog:
* rust/compile/nr2/exclude: nr2 cant handle this
* rust/compile/cmp1.rs: New test.
