75406ad5be Move signatures into new ir::extfunc module. 
This new module will gain more data types dealing with external function
calls.

e5080fb64e Use 'varargs' consistently for VariableArgs members. 
The meta code generators need to be able to infer these too.

eeb6fe0983 Track InstructionData member names. 
Entity references in instruction format operands also have member names
in the InstructionData struct. Track them the same way we track immediate operand member names.

Value operands still go in the arg / args members.

620f46202f Define AST nodes and instruction transformations. 
Enable syntax: iadd(x, y) which creates an Apply node.
Enable syntax: z << iadd(x, y) which creates a Def node.

Add an XForm class which represents source and destination patterns as
RTL lists.

4db11d1ae7 Add legalization helper instructions. 
The isplit_lohi instruction breaks an integer into two halves. This will
typically be used to get the two halves of an `i64` value on 32-bit
CPUs.

The iconcat_lohi is the reverse operation. It reconstructs the `i64`
from the low and high bits.

These classes are not very entangled with the rest of __init__, and
we'll be expanding them a bit.

f34da59bab Integer subtraction with borrow flags.

which inverts the sense of the carry flag.

ce0da25ce0 Write out encoding annotations on instructions. 
All instructions with associated encodings are now annotated with
encoding information in a column before the code.

When write_function() is givan a TargetIsa reference, the annotations use
ISA-specific names. Otherwise everything is numeric.

2ec50203fb Print encodings as [R#10c] instead of [R/10c]. 
The # is a more conventional prefix for hexadecimal, and when ISA
information is not available, there may be a decimal number in front
which would be confusing.

So prefer [1#10c] for the ISA-less encoding format. Here '1' is decimal
and '#10c' is hexadecimal.
