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.

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.

d6ac351dcb Add --public-flat-rw switch, bug1511. 
This switch exposes VARs, PORTs and WIREs to C++ code. It must be use
with care as it has a significant performance impact and may result in
mis-simulation of generated clocks. Anyhow, it is prefered over
--public and useful for VPI.
