Instruction mismatch errors have been held until the last assembly
pass in case changed %if statements cause a code path to be elided in
subsequent passes. However, it is confusing to the user if error
messages aren't shown if another error terminates assembly.
Use the already existing mechanism for warnings to hold the messages
unless another error terminates assembly.

The ret.asm test was broken because the assembly expected -DERROR=1
whereas the run script provided -DERROR, masking all the actual
errors...

Always generate a list file and point output at a given filename, even
if failure is expected.
Remove ad hoc -o output names that generally don't point into safe
locations.
The result is that the preprocessing options (-E) no longer output to
stdout, so change the tests accordingly.

Don't stop travis after a single test failure. It is better to run all
the tests and get a comprehensive list of failing tests.

All the 16 AMX-TRANSPOSE instructions were removed from the 59th
edition of "Intel Architecture Instruction Set Extensions and Future
Features Programming Reference" September 2025, 319433-059.
Similar to PCOMMIT, they are tagged as 'NEVER'
[ hpa: don't remove from tests, but suppress the warnings. Don't
remove the CPUID tag; a future version of NASM will actually implement
CPU filtering based on the various CPUID tags; that development is
genuinely in progress. ]

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.

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
