07f9fe6ee4 C++: Add Uninitialized instruction for list-initialized variables 
This commit inserts an `Uninitialized` instruction to "initialize" a local variable when that variable is initialized with an initializer list. This ensures that there is always a definition of the whole variable before any read or write to part of that variable.

This change appears in a different form in @rdmarsh2's Chi node PR, but I needed to refactor the initialization code anyway to handle ConditionDeclExpr.

f278f4fa47 C++: Operands as IPA types 
@rdmarsh2 has been working on various queries and libraries on top of the IR, and has pointed out that having to always refer to an operand of an instruction by the pair of (instruction, operandTag) makes using the IR a bit clunky. This PR adds a new `Operand` IPA type that represents an operand of an instruction. `OperandTag` still exists, but is now an internal type used only in the IR implementation.

93732d8b5a C++: Combine IR guard tests into one ql file 
This is motivated by test performance; IR compilation happens separately
for each test and takes a bit over a minute, so combining these 8 tests
saves about 10 minutes of test running.

f323fa1df8 C++: test changes from previous commit 
The IR for the conversion to bool results in a comparison where the left
hand side is not the result of any expression in the AST, so they can't
be usefully converted back to the AST

d7e630b3c6 C++: Add IR-based port of Guards library 
For ease of reviewing, I've checked in the .expected files from the
AST-based guards library. The next commit accepts output for these tests
and adds tests that use getAST rather than the translation layer.

43f0289f0f C++: Remove Phi instructions from previous IR generations 
It turns out that when building aliased SSA IR, we were still keeping around the Phi instructions from unaliased SSA IR. These leftover instructions didn't show up in dumps because they were not assigned to a block. However, when dumping additional instruction properties, they would show up as a top-level node in the dump, without a label.
