Merge pull request #17647 from dlongnecke-cray/next-add-local-serial

Add headers/implementation for Local/Serial nodes, adjust parser rules (#17647)

This is for compiler/next.

Adds AST interfaces for local statements and serial statements, as
well as support for parsing them.

The AST interfaces for local and serial provide a method usesDo
which returns true if the construct was parsed from the following
sort of code:

local foo do {
  var x;
}

This may prove useful when building a linter in the future.

In the parser, add a rule called block_stmt_body which collects the
contents of a block (including comments) into a ParserExprList
without creating a Block AST node. This enables "block-like" nodes
such as local and serial to easily lift the statements in a block
into their own child statement list.

In the parser, make the rule do_stmt return a structure called
BlockOrDo. This contains a list of child statements as well as a
flag indicating whether or not the statements were preceded by the
'do' keyword. This may prove useful when parsing other "block-like"
statements.

Add tests testParseLocal.cpp and testParseSerial.cpp.

TESTING:

  • [x] All compiler/next tests pass
