Unsized expressions can expand to extremely large widths. Usually this is actually a mistake in the source code, but it can lead to the compiler temporarily using extremely large amounts of memory, or in the worst case, crashing. This adds a cap on the width of unsized expressions (by default 65536 bits, but overridable by the user), and causes a warning message to be output when the cap is reached.
