write_verilog: do not print (*init*) attributes on regs.
...
If an init value is emitted for a reg, an (*init*) attribute is never
necessary, since it is exactly equivalent. On the other hand, some
tools that consume Verilog (ISE, Vivado, Quartus) complain about
(*init*) attributes because their interpretation differs from Yosys.
All (*init*) attributes that would not become reg init values anyway
are emitted as before.

backends: smt2: use $(CXX) variable for compiler
...
The Makefile assumes the compiler is called `gcc`, which isn't always
true. In fact, if we're building on msys2 or msys2-64, the compiler
is called `i686-w64-mingw32-g++` or `x86_64-w64-mingw32-g++`.
Use the variable instead of hardcoding the name, to fix building on
these systems.
