The GNU extensions to C/C++ are not required to build Verilator. Note
this change does not affect __attribute__, __builtin_* and intrinsics,
which are still available when using GCC or Clang with the standard
language options.

patch restores them by adding --enable-coverage to configure and

Compile the debug build with -Og -ggdb -gz if supported.
...
Check the C++ compiler for -Og via configure and use it if available.
Per the GCC manual:
-Og should be the optimization level of choice for the standard
edit-compile-debug cycle, offering a reasonable level of optimization
while maintaining fast compilation and a good debugging experience. It
is a better choice than -O0 for producing debuggable code because some
compiler passes that collect debug information are disabled at -O0.
The debug exe is painfully slow on large designs, hopefully this is an
improvement.
Similarly, check for and use -gz to compress the debug info as it is
huge otherwise. This should help with distribution and caching on CI.
Also checks for -ggdb via configure for compatibility.

Link Verilator binary partially statically, Closes #2146 .
...
The build is now by default configured to link performance critical
libraries (libgcc, libstdc++, libtcmalloc) statically. This improves
Verilation speed by between 4.5-7% based on my measurements as it
eliminates approx 20% of the mispredicted branches from the execution.
With partial static linking, the size of the .text section in
verilator_bin is increased by about 14%, and the binary is itself only
about 800KB bigger on disk, so hopefully this is not a big issue in
exchange for the faster compilation speed. A configure option
"--disable-partial-static" is provided to restore the old behaviour of
linking everything dynamically.
Note: This patch also changes to use libtcmalloc_minimal, which is all
we really need and itself has fewer dependencies.

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.
