15d6a9a17e attr,build: add TOPFRAME attribute (#98)
Go added the TOPFRAME attribute in https://golang.org/cl/169726/. This diff adds the new attribute to avo, and also updates handling of the REFLECTMETHOD attribute.

d43efabdbe inst,ir: cancelling inputs (#92)
Adds support for a `CancellingInputs` instruction flag, to indicate cases like `XORQ R10, R10` where the instruction actually does not depend on the value of `R10` at all.

Closes #89

2e7d06bc7a pass: remove redundant jumps and dangling labels (#81)
In jump-table-like constructs, the natural way of writing the code can sometimes produce redundant jumps or labels. Therefore some basic cleanup steps have been proposed. This diff adds two transforms:

1. Remove unconditional jumps to a label immediately following.
2. Remove labels with no references at all.

Fixes #75

57c23b967e pass: add PruneSelfMoves cleanup pass (#80)
In some cases natural use of abstraction in avo programs can lead to redundant move instructions, specifically self-moves such as MOVQ AX, AX. This does not produce incorrect code but it is incorrect and inelegant.

This diff introduces a PruneSelfMoves pass that removes such unnecessary instructions.

Closes #76

220969f8c8 internal/load: support additional MOVQ forms
The Go assembler merges MOVD/MOVQ instruction forms. The logic in the
avo instruction loader was discarding the MOVD forms. This diff should
merge them correctly.

Run asmfmt suring linting and confirm git repository isn't dirty.

304c7425d2 build: add attributes argument to TEXT

in assembly.

602bb5197c build: unify Label function signatures
The Context.Label method and LABEL global function did not agree. Also
breaks the convention I'd like to set that capitalized functions must
agree with existing Go assembly syntax.

To help avoid a conflict with `avo.Label`, attributes were moved to
their own package.

18cdf50d7c reg: support for register casting
Adds methods for referencing sub- or super-registers. For example, for
general purpose registers you can now reference As8(), As16(), ... and
for vector AsX(), AsY(), AsZ().
