	  Add passing N3886 audit test cases for expression operands,
	  declarations, labels, jumps, returns, function definitions,

	  for host diagnostic differences.

	* src/SDCCast.c (decorateType): Diagnose structure and union operands
	  of casts to non-void types (bug #4089).
	* src/SDCCerr.c, src/SDCCerr.h: Add E_CAST_NONSCALAR. Clarify that
	  E_CAST_ILLEGAL concerns the destination type, avoiding "aggregate".
	* support/valdiag/tests/bug-4089.c: Test structure and union operands,
	  casts to void, and array and function decay.

	* src/SDCCast.c (decorateType): Diagnose casts from pointer to
	  floating-point type (bug #4088).
	* src/SDCCerr.c, src/SDCCerr.h: Add E_CAST_PTR_TO_FLOAT as an error.
	* support/valdiag/tests/bug-4088.c: Add a test that expects an error
	  when an expression of type int * is cast to type float.

	* src/SDCCval.h, src/SDCCval.c (stringInitializerTypesMatch): Compare
	  string and destination element type compatibility, allowing ordinary
	  character arrays and compatible wide types (bug #4189).
	* src/SDCCast.c (createIvalCharPtr), src/SDCCglue.c (printIvalArray):
	  Diagnose incompatible string initialisers before reading their elements.
	  Limit the direct-array check to scalar character and integer elements;
	  preserve pointer-element and nested-array initialisation.
	* support/valdiag/tests/bug-4189.c: Check mismatched types, braces,
