Support disable statements and system task calls in constant functions.
...
This patch implements the evaluate_function method for the NetDisable
and NetSTask classes. It also makes the checks for a function being
constant work when the function contains nested scopes (named blocks).

Handle implicit cast when short-circuiting ternary expression.
...
If a ternary expression with mixed logic and real operands is
short-circuited and the logic value is selected, that value
should be cast to a real value.

Fix implicit casts in assignments (part 1).
...
This patch adds support for implicit casts to the elaborate_rval_expr()
function. This will handle the majority of cases where an implicit cast
can occur.

Eliminate duplicate error messages for indexed part selects.

This patch stops the compiler generating duplicate error messages
when an indexed part select has an illegal width.

Handle error case of zero width in indexed part select.
...
The compiler doesn't currently check that the width of an indexed
part select is non-zero. If code contains this erroneous case, the
compiler can crash (with an assertion failure). This patch causes
the compiler to output a suitable error message and recover. It
also fixes a potential crash if an illegal expresson is encountered.

Allow specparam declarations outside specify blocks.

This patch extends the compiler to support all specparam declarations
allowed by the 1364-2005 standard. For compatibility with other
simulators, it allows specparam values to be used in any constant
expression, but outputs a warning message and disables run-time
annotation of a specparam if it is used in an expression that must
be evaluated at compile time.
