gccrs: Added HIR::InlineAsm node

Fixes Issue #1568
Added HIR node HIR::InlineAsm similar to the one found in rustc. In this
I also changed the defination of the AST::InlineAsm node, so that we can
reuse many of it's data members in the HIR::InlineAsm node.

gcc/rust/ChangeLog:

	* ast/rust-ast-full-decls.h (enum class): Added declaration.
	(struct AnonConst): Added declaration.
	(struct InlineAsmRegOrRegClass): Added declaration.
	(struct InlineAsmOperand): Added declaration.
	(struct InlineAsmPlaceHolder): Added declaration.
	(struct InlineAsmTemplatePiece): Added declaration.
	(struct TupleClobber): Added declaration.
	(struct TupleTemplateStr): Added declaration.
	* ast/rust-expr.h (class InlineAsm): Defined all it's data members outside.
	(enum class InlineAsmOptions): Converted this to a enum class so we could use it in the HIR.
	(struct AnonConst): Defined it independent of the AST::InlineAsm node.
	(struct InlineAsmRegOrRegClass): Defined it independent of the AST::InlineAsm node.
	(struct InlineAsmOperand): Defined it independent of the AST::InlineAsm node.
	(struct InlineAsmPlaceHolder): Defined it independent of the AST::InlineAsm node.
	(struct InlineAsmTemplatePiece): Defined it independent of the AST::InlineAsm node.
	(struct TupleClobber): Defined it independent of the AST::InlineAsm node.
	(struct TupleTemplateStr): Defined it independent of the AST::InlineAsm node.
	* hir/tree/rust-hir-expr.h (class InlineAsmReg): Added defination.
	(class InlineAsmRegClass): Added defination.
	(struct InlineAsmRegOrRegClass): Added defination.
	(class InlineAsm): Added defination.
	* hir/tree/rust-hir-full-decls.h (class InlineAsmReg): Added declaration.
	(class InlineAsmRegClass): Added declaration.
	(struct InlineAsmRegOrRegClass): Added declaration.
	(class InlineAsm): Added declaration.
