1. Every `ASTNodeUP` is asserted before being used in creating another
`ASTNodeUP`.
2. Removed returning `nullptr` in `ParseIntegerLiteral` and
`ParseFloatingPointLiteral` to avoid confusion.
3. All `ASTNodes` are now passed by reference instead of pointer.
This is an alternative to
https://github.com/llvm/llvm-project/pull/159500, breaking that PR down
into three separate PRs, to make it easier to review.
This first PR of the three adds the basic framework for doing type
casing to the DIL code, but it does not actually do any casting: In this
PR the DIL parser only recognizes builtin type names, and the DIL
interpreter does not do anything except return the original operand (no
casting). The second and third PRs will add most of the type parsing,
and do the actual type casting, respectively.
This adds the ability to recognize (and create ValueObjects for) boolean
literals ("true", "false") to DIL. This is a preliminary step to adding
type casting (and also for the ternary op).
This patch introduces `ScalarLiteralNode` without any uses by other
nodes yet. It also includes lexing and parsing for integer and floating
point numbers.
Reapplies #152308 with a fix.
This patch introduces `ScalarLiteralNode` without any uses by other

Add the Data Inspection Language (DIL) implementation pieces for
handling plain local and global variable names.
See https://discourse.llvm.org/t/rfc-data-inspection-language/69893 for
information about DIL.
This change includes the basic AST, Lexer, Parser and Evaluator pieces,
as well as some tests.
