What previously used to be per module static constants created in
V3Table and V3Prelim are now merged globally within the whole model and
emitted as part of a separate constant pool. Members of the constant
pool are global variables which are declared lazily when used (similar to
loose methods).
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.
Using the standard model Makefile, when in addition to an explicit
target, the target 'ccache-report' is also given, a summary of ccache
hits/misses during this invocation of 'make' will be prited at the end
of the build.
Reasons are:
- it's error prone to keep updating whennever m_suffixes is resized
- invalid pointer may be set when there is not signal to trace as in t_trace_dumporder_bad
* Add VL_ATTR_NO_SANITIZE_ALIGN macro to disable alignment check of ubsan
* Mark a function VL_ATTR_NO_SANITIZE_ALIGN because the function is intentionally using unaligned access for the sake of performance.

The "file" make function is only available in gmake 4.x, which isn't
available on RHEL/CentOS 7. Use alternative syntax to support older
gmake versions.
Fixes#2920
** Add simulation context (VerilatedContext) to allow multiple fully independent
models to be in the same process. Please see the updated examples.
** Add context->time() and context->timeInc() API calls, to set simulation time.
These now are recommended in place of the legacy sc_time_stamp().
