The vvp reduction operators evaluate their input bit by bit. This is
expensive for wide vectors.
Add word wide reduction helpers to `vvp_vector4_t` and use them for both
reduction functors and vthread reduction opcodes.

The logic functors combine their input vectors bit by bit.
Use the in-place `vvp_vector4_t` operators for the vector operation and
invert the result once for the inverted functors.

The vthread binary logic opcodes update vectors bit by bit.
Use the in-place `vvp_vector4_t` operators instead. This reuses the word
wide implementation and avoids per-bit `value()` and `set_bit()` calls.

`vvp_vector4_t` has word wide in-place operators for and and or, but not
for xor.
Add `operator ^=` using the same internal word representation.

When running `make check` on a UNIX-like operating system
with the specified `configure` option, `vvp` was unable to
find the required shared library.
This commit ensures that the runtime linker can locate the library.
This fixes issue #1313.
The vvp/ivl_dlfcn.h and cadpli/ivl_dlfcn.h files are essentially the
same, but have diverged a bit over the years. Merge them into a single
shared file at the top level. Use the static prefix for all inline
functins (currently only used in the cadpli version) as that will fix
issue #1301. We now require the compiler to support at least C99, so
can use "inline", not "__inline__".
The clang dlltool is not compatible with the binutils dlltool. However
both the clang and binutils linkers support reading the .def file and
creating the import library directly, so we no longer need to perform
the link in two stages.
We need to build libvvp with a suffix from the outset to ensure that
the vvp binary searches for the correct library file name once it is
installed.
Also Windows DLLs need to be stored in the same directory as the main
program, not in a separate lib directory.
Commit 95810b2f61 mistakenly added the suffix to the output file name
when linking the final vvp.exe binary. 'make check' and 'make install'
assume the suffix is only added when installing.
The tgt-vvp code generatpr outputs identifiers as quoted strings, and
because of this, escapes any " and \ characters (which may appear in
escaped indentifiers). We need to undo this when reading them into
vvp, so that the original name is seen by the VPI routines.
