Modified grammar in parse.y to use identifier_name instead of IDENTIFIER
in function/task declaration rules and hierarchy_identifier rule. This
allows TYPE_IDENTIFIER tokens (which class names become after definition)
to be used as method names.
Changes:
- Function declaration rules (lines 1585, 1605, 1631)
- Task declaration rules (lines 2445, 2472, 2501)
- hierarchy_identifier member access (line 4471)

When $bits() is called with an undefined identifier, the compiler now
properly reports an error instead of silently returning 0.
The fix checks if the argument expression has type IVL_VT_NO_TYPE after
test_width() processing (indicating the identifier couldn't be resolved),
and triggers elaboration to produce a proper error message.

Currently, when a constant bit/part select is found in the implicit
sensitivity list for an always_* construct, it is replaced by the
entire signal. If there is more than one bit/part select from the
same signal, that signal gets added to the list multiple times. This
breaks the algorithm used to detect duplicate events in the nodangle
functor, causing it to erroneously merge non-identical events in some
cases.
The proper fix is to support sensitivity at the bit/part level, as
required by IEEE 1800. But for now, just make sure we only include
the entire signal once, regardless of how many different bit/part
selects we find. Enhance the "sorry" message to report which signals
are contributing excessively to the process sensitivity.
Also allow extra configuration options to be passed via the
IVL_CONFIG_OPTIONS environment variable and add some missing
dependencies. Don't include --enable-libveriuser by default.
Update the README accordingly, with sensible line wrapping.
This version works with the native Windows (mingw64 and clang64)
versions of Perl in MSYS2.
Note that warnings are disabled in the Environment.pm module because
Perl fails to notice that OLDOUT and OLDERR are used when restoring
the STDOUT and STDERR file handles.
