Geza Lore 209a585a68 Remove VL_NEGATE_{I,Q,E}, use C native unary '-' instead
This is to avoid slowing down -O0 models unnecessarily.

Support IEEE time units and time precisions, #234. (#2253)
Includes `timescale, $printtimescale, $timeformat.
VL_TIME_MULTIPLIER, VL_TIME_PRECISION, VL_TIME_UNIT have been removed
and the time precision must now match the SystemC time precision.
To get closer behavior to older versions, use e.g. --timescale-override
"1ps/1ps".

Fix to make trace code allocation dense. (#2250)
This looks like a bits/bytes bug. The affected m_codeInc member
determines how many 32-bit words to allocate in a buffer used to store
previous values of the signal, but this was off by a factor of 8, so
we used to use too much memory.

SweRV VCD tracing speed +6.5% (excluding IO, clang 6.0), due mainly to
reduced D cache misses.

Geza Lore ef5250f0ca Internals: Further performance improvement of AstNode type tests, #2138. No functional change intended.
Replace the virtual type() method on AstNode with a non-virtual, inlined
accessor to a const member variable m_type.  This means that in order to be
able to use this for type testing, it needs to be initialized based on the
final type of the node. This is achieved by passing the relevant AstType
value back through the constructor call chain. Most of the boilerplate
involved is auto generated by first feeding V3AstNodes.h through astgen to
get V3AstNodes__gen.h, which is then included in V3Ast.h. No client code
needs to be aware and there is no functional change intended.

Eliminating the virtual function call to fetch the node type identifier
results in measured compilation speed improvement of 5-10% as it
eliminates up to 20% of all mispredicted branches from the execution.

Geza Lore 220daa5f33 Internals: Restore AstNode naming property. #2133.
The intention was that all subclasses of AstNode which are
intermediate must be abstract as well and called AstNode*. This was
violated recently by 28b9db1903. This
patch restores that property by:
- Renaming AstFile to AstNodeFile
- Introducing AstNodeSimpleText as the common base of AstText and
  AstTextBlock, rather than AstTextBlock deriving from AstText.
