* Start adding the load_complex and store_complex instructions.
N.b.:
The text format is not correct yet. Requires changes to the lexer and parser.
I'm not sure why I needed to change the RuntimeError to Exception yet. Will fix.
* Get first few encodings of load_complex working. Still needs var args type checking.
* Clean up ModRM helper functions in binemit.
* Implement 32-bit displace for load_complex
* Use encoding helpers instead of doing them all by hand
* Initial implementation of store_complex
* Parse value list for load/store_complex with + as delimiter. Looks nice.
* Add sign/zero-extension and size variants for load_complex.
* Add size variants of store_complex.
* Add asm helper lines to load/store complex bin tests.
* Example of length-checking the instruction ValueList for an encoding. Extremely questionable implementation.
* Fix Python linting issues
* First draft of postopt pass to fold adds and loads into load_complex. Just simple loads for now.
* Optimization pass now works with all types of loads.
* Add store+add -> store_complex to postopt pass
* Put complex address optimization behind ISA flag.
* Add load/store complex for f32 and f64
* Fixes changes to lexer that broke NaN parsing.
Abstracts away the repeated checks for whether or not the characters
following a + or - are going to be parsed as a number or not.
* Fix formatting issues
* Fix register restrictions for complex addresses.
* Encoding tests for x86-32.
* Add documentation for newly added instructions, recipes, and cdsl changes.
* Fix python formatting again
* Apply value-list length predicates to all LoadComplex and StoreComplex instructions.
* Add predicate types to new encoding helpers for mypy.
* Import FieldPredicate to satisfy mypy.
* Add and fix some "asm" strings in the encoding tests.
* Line-up 'bin' comments in x86/binary64 test
* Test parsing of offset-less store_complex instruction.
* 'sNaN' not 'sNan'
* Bounds check the lookup for polymorphic typevar operand.
* Fix encodings for istore16_complex.
