Add a {rex} prefix to force REX encoding (typically a redundant 40h
prefix).
For prefix parsing, we can use t_inttwo to encode the prefix slot
number.
Give more verbose error messages for encoding mismatches.
If macro is undefined while it's being expanded, use after free occurs,
since the MMacro instance is released, but it is still used to proceed
the expansion.
This change forbids macro undefinition: non-fatal error is raised and
the MMacro instance is not released if it is being processed by NASM
preprocessor.
Consider the following example:
| $ cat test.asm
| %macro m 0
| %unmacro m 0
| %endmacro
| m
| $ ./nasm test.asm
| test.asm:4: error: `%unmacro' can't undefine the macro being expanded
| test.asm:2: ... from macro `m' defined here

Lets run it as win32 since they are sharing
backends in most places but win32 is a way
more widely used.

It is failing right now so I'm not sure if
masm test is correct one. Lets merge it in
this form and update if needed.

Currently we strip newlines from files on read and write
procedures for better diff output, but as being pointed
by hpa@ this makes quite inconvenient to work with tests
in a manual mode.
Thus lets left outputs as is. We have to update all tests
with template outputs since by default output streams are
ending with newline.

We need the ability to produce consistent output for our own tests,
anyway, so make this a user-accessible feature. This was requested in
BR 3392635.
This obsoletes the NASM_TEST_RUN environment variable; simply use the
normal NASMENV environment variable instead.
The .obj tests in travis needed to be updated in order to remove the
rather pointless suffix " CONST" from the NASM signatures.

The "warnstack" test is supposed to test the warning stack, but the
[warning] directive is never seen in preprocess-only mode, so run it
in -f bin mode.

%ifid $ and %ifid $$ has traditionally been false, revert to that
behavior.
