Update and improve the build from source documentation, including add
an auto-generated list of Perl build dependencies.

Document CPU LATEVEX and the associated prefixes; add CPU EVEX and CPU
VEX flags to further control encodings.
Fix the error message for invalid encodings due to flags.

Bring doc/changes.src up to date with the current status of tree in
preparation for the 2.16 release.
Note that no 2.15.06 release ever was produced.

RDOFF has been deprecated as it has unfixable problems, and has been
announced that it will be killed off in NASM 2.16.
This deletes it once and for all.

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.

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

The RDOFF backend has been broken since at least NASM 2.14, throwing
an immediate assert. Since only one person appears to have even
noticed, and fixing it properly looks like it would take quite a bit
of work, disable this back end and document its deprecation.

$ in data expressions is hazardous. A proper fix for this turns out to
be quite complex, as it requires the expression engine to propagate
additional data. For now, just put it into the documentation.

BNDMK, BNDLDX, and BNDSTX are split-SIB (MIB) instructions, but do
*not* require a SIB encoding. However, TILELOAD* and TILESTORE* *do*
require a SIB in all cases. Split the MIB flag into MIB (split
address) and SIB (SIB required) flags.
This fixes travis test mpx.

We need to add the byte offset into the floating-point value to get
the correct result for these floating point to integer conversions.

-Lw really is only useful to debug NASM crashes, and can hugely slow
down the assembler. Make -L+ simply imply full verbosity; if NASM
crashes use -Lw+ instead.

Most SSE instructions were missing memory operand sizes, resulting in
error if a memory operand was specified with explicit size.

The %? and %?? tokens are ambiguous when used inside a multi-line
macro. Add tokens %*? and %*?? that only expand during single-macro
expansion.

Support generating bfloat16 constants. This is a bit awkward, as "DW"
already generates IEEE half precision constants; therefore there is no
longer a single floating-point format for each size. This requires
some replumbing.
Fortunately bfloat16 fits in 64 bits, so support generating them with
a macro that uses __?bfloat16?__() to convert to integers first before
passing them to DW.
