Handle mixed continuous and non-blocking assignments to same vector.
...
SystemVerilog allows a mixture of procedural and continuous assignments
to be applied to different parts of the same vector. The previous attempt
to make this work for non-blocking assignments was flawed (see preceding
fix for vvp_fun_part_pv::recv_vec4_pv). Instead, handle this case by
converting the non-blocking assignment into a delayed force statement,
which matches the way mixed continuous and blocking assignments are
handled.

Fix printf format for size_t values when using 64-bit MinGW.
...
The Microsoft C runtime does not support the %zu and %zd formats.
Previously these were replaced with %u and %d, but for 64-bit we
need to use %llu and %lld.

Fix for br968.
...
__vpiVThrVec4Stack::vpi_get_value_int_ was always treating the thread variable
as unsigned, rather than observing the value of __vpiVThrVec4Stack::signed_flag_.
Not sure why this was done - none of the regression tests broke when I changed
this.

Fix potential memory leak when a thread is disabled.
...
A disable statement can terminate a thread whilst it still has
local variables on the stack (e.g. the loop counter for a repeat
statement). We need to clear the thread stacks when this happens.

Use uint64_t casting of constants since UL does not work on 32-bit machines
...
Using a UL constant in a unit64_t context does not work on a 32-bit
machine since UL is 32-bits. Instead create uint64_t constants using
static casts and the appropriate bit operators.
