28b080d9bc + emit a size directive for the internal dynarray const label. This fixes 
WebAssembly dynarray consts with the llvm-mc external asm.

12bde4e903 WPO: fix dead code detection, and handle procvars 
Extend dead code detection to not only look for the main mangled name, but also
for any aliases before deciding that a routine has been dead-stripped.

Assume objects/classes can also be constructed if the address of one of their
constructors or of the TObject.NewInstance class method has been taken.

Resolves #40204

b1f85792d7 Symbolic constants: don't range check on in use in typed constants 
Same as 3da54dcf9f, but this type when used in type constant definitions

ab01b0ebd7 Typed constants: no internalerror on failure 
Don't check whether the expression queue is empty in the destructor in case
there was an error. Also improved error messages (constant expression instead
of variable expression expected).

0ca1e2fb42 * attempt to fix bitpacked records with qwords in them (tw36156) when cross-compiling to big endian targets from x86. essentially the x86 shifting workarounds in the code already weren't covering all corner cases.

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

c038e4c3f2 * relaxation of r42272: again only show warnings rather than errors for 
out-of-range constants, because of the comments mentioned in #35753
    (except for enums, as apparently Delphi does the same)
  * added range check warnings about explicit type casts that throw away
    bits (e.g. byte($fff)), without giving warnings for most common cases
    (like cardinal(-1))
  * fixed masking/sign exting constant array indices (must be based on index
    range type size/signedness rather than on array size/"signedness")
