all the parameters, and only after that, push them on the stack. This avoids

* WebAssembly internal linker: refactored the writing of the memory section and

the memory import section: introduced a TWasmMemoryType record, and structures
for holding the memory entries in the import and memory sections, instead of
writing them in an ad hoc manner. The memory information in the linker map
file is now also a little more detailed.

- WebAssembly code generator: removed the g_fingerprint hack, that added 4
...
useless i64 constants on the stack with random numbers and then drop them. It
was used for primitive debugging, since previously it wasn't possible to
identify the function name. Now we can produce DWARF debug info, as well as a
"names" custom section to give each function a name and most WebAssembly
environments support at least one of the two mechanisms. Therefore the
g_fingerprint hack is no longer necessary.
