The label-orphan warning is *way* more useful if it includes the
actual label name; this way the programmer can usually spot
immediately if it is a label or misspelled instruction.

Officially the syntax for TEST is "rm,reg"; however TEST is
commutative in every aspect, and as such "reg,mem" is an equivalent
form that NASM has also supported in the past.
Reinstate it properly.

If a line is suppressed, the %if or %rep condition must never be
evaluated. Test for it, and add the exitrep test to travis.

The assembler can't know if something is a colonless label or a
misspelled instruction, so print both when complaining about a missing
instruction.

A pattern for XCHG was incompletely macroized. This caused a
fallthrough to the next pattern, reversing the operands, but would
probably have had generated incorrect code in at least some cases.
Beef up the xchg test.

ADC and SBB don't support using the {nf} prefix. They are the only one
in the arithmetic instructions group that are this way.
Add a flag that will warn when an instructions wants to use {nf} but
doesnt' support it.

I missed that LZCNT can use REX2, two other TODOs were fixed by changes
made by Peter in between my patches.

Add the database entry for CTESTcc and the relevant test cases. The
syntax is basically CCMPSCC without two syntax variants.

Start splitting of tests to other files because the apx.asm is getting
very big and hard to read when multiple errors happen.

The external call to hexdump was broken and would hang if the output
exceeded the host operating system size limit. Since it *anyway*
was reading the entire dump into RAM, just rewrite it in native
Python.

The last testcase hangs the travis test system. The cfcmovb rv rv syntax
seems to cause problems for some reason.

Making DEFAULT ABS the default for 64-bit mode was a real
mistake. Issue a warning so we can eventually change it.
Support making FS: and GS: references also be REL by default.
