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 7ab2bdb6bb Support libgoogle-perftools-dev's libtcmalloc if available. #2137.
As Verilator continuously allocates and releases small objects (e.g.:
AstNode, V3GraphVertex, V3GraphEdge), it spends a significant amount of
time in malloc/free and friends. This patch adds the --enable-tcmalloc
configure option to link Verilator against the high performance malloc
implementation library libtcmalloc. The default is to use libtcmalloc if
available on the system. Note that there are no source code change, we
are simply replacing the standard library memory allocation functions.

Measured major compilation speed improvement of 27% when running
Verilator with -O3 on a large design.

Add lint_off -match waivers (#2102)
* Add more directives to configuration files

Allow to set the same directives in configuration files that can also
be set by comment attributes (such as /* verilator public */ etc).

* Add support for lint messsage waivers

Add configuration file switch '-match' for lint_off. It takes a string
with wildcards allowed and warnings will be matched against it (if
rule and file also match). If it matches, the warning is waived.

Fixes #1649 and #1514
