Some of the IR classes require setters in order to update dependant
information. In order to keep the IR access symmetrical this CL moves
the IR back to using accessors and private fields.

This CL updates the IR builder to deduplicate constants such that for a
given constant value only a single `ir::Constant` will be created.

When converting an AST expression to IR, check for a sem::Load node
and emit a load instruction if present.
Update conversion of compound assignment and increment/decrement to
load from the LHS.
Convert load instructions to inline variable references when going
back to the AST.

This CL adds phony assignment to the IR. The assignment part is ignored
and the RHS of the expression is generated. This creates a result value
which is then never used.

The ShortCircuit is updated to use block arguments instead of creating

The address space and access mode both exist on the type of the Var,
storing the information into Var is redundant. This CL removes them from
var in favour of the type fields.

The scope stack for a loop is slightly different from other constructs
as the block for the body and the block for the continuing need to share
the scope. This CL fixes the loop conversion to special case the scope
stack for the loop body so the continuing block can see the variables.

Black-box the BuilderImpl by putting the BuilderImpl into the
from_program.cc file.
Why:
* It means there's only a single definition of all the methods that need
to be maintained, instead of pointlessly splitting code between two
files (.cc / .h).
* It removes all the implementation details from the header.
* It removes a whole bunch of transitive includes, slowing compiles.
* It prevents the temptation for future #includes to
private-implementation details.
* It reduces the amount of symbols declared outside of anonymous
namespaces, reducing symbol polution and the amount of work on the
linker.

ToProgram() will most likely be conditionally compiled as a separate .h
and .cc file. With just one static method, ir::Converter doesn't make a
lot of sense to be a class. Just replace with a free-function.
