Matthew Ballance 7bc6d8a602 CMake: detect PCH include flag for GCC/Clang in verilated.mk 
Without this, CFG_CXXFLAGS_PCH_I was left empty in CMake builds, causing
GCC to treat the PCH filename as a linker input instead of applying it as
a -include flag, breaking compilation of any model that uses PCH.

This is a general CMake build fix (not funccov-specific); the same bug
exists in upstream CMakeLists.txt. It is included here because funccov's
cross-coverage tests expose the issue.

Matthew Ballance 20970c7dde Add function coverage (funccov) and covergroup support 
Implement functional coverage collection via covergroups, coverpoints,
and cross coverage bins. Introduces V3CoverageFunctional pass and
verilated_funccov.h runtime support.

Optimize Ast read references in Dfg directly (#7354) 
Introduce a new DfgAstRd vertex, which holds an AstNodeExpr that is a
reference to a variable. This enables tracking all read references in
Dfg, which both enables more optimization, and allows inlining of
expressions in place of the reference more intelligently (e.g, when the
expression is only used once, and is not in a loop). This can get rid of
20-30% of temporary variables introduced in Dfg in some designs. Note
V3Gate later got rid of a lot of those, this is a step towards making
V3Gate redundant. The more intelligent expression inlining is worth ~10%
runtime speed on some designs.
