Matthew Ballance 07f959d31d Refactoring node locations and enums ; Delete coverpoints after V3Covergroup so they don't accidentally hit the generators

Matthew Ballance 1ee88a0c79 Revert V3Coverage.cpp to funccov-minimal merge base 
The VLifetime::AUTOMATIC_EXPLICIT addition is not required for
functional coverage — all 60 covergroup tests pass without it.

Matthew Ballance 5ef2a2956d Revert V3EmitV.cpp and V3LinkInc.cpp to funccov-minimal merge base 
These changes are not required for functional coverage support and
should not be included in the upstream patch.

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.
