Stephen Williams 373123af6b Detect thread bit allocation failures
Detect thread bit allocation failures and fail gracefully. Print an
error message that points at the expression in question, and return
with an error code so that the compiler exits with an error.

Cary R ded0fbe5ef Fix user functions with right shift argument.
A right shift may generate extra bits to preserve the proper shift
characteristic. This patch replaces the assert that was forcing the
input vector to not be greater than the input port width with code
to only select the required lower bits from the vector if it is
larger than the input port.

Stephen Williams 1506a0bf8c Pad type-punned user functions properly
When user defined function calls are withing a $signed, the result
needs to be properly padded. To make this work, handle padding of
a function result exactly type the padding of a signal vector. this
is natural in that the function return value *is* in a signal vector.

This fixes pr1841300.

Stephen Williams d7c3a32b06 Fix code generation for real expressions
Real value are vector width of 1, fix real literal to reflect this.
fix leaking real registers in code generation for function arguments.
Load of signal should handle conversion from real to vector. Function
arguments, type vector passed a real value, are an example where this
comes up.

steve 91d84e7dc7 Major rework of array handling. Memories are replaced with the
more general concept of arrays. The NetMemory and NetEMemory
 classes are removed from the ivl core program, and the IVL_LPM_RAM
 lpm type is removed from the ivl_target API.
