wasm2c: harmonize bulk mem ops re: i32/i64 (#2506) + parametrize memchecks per-memory (#2507)HEADmain
The PR updates the bulk memory operations (memory.fill, memory.copy,
table.fill, etc.) to support 64-bit addresses and counts. Previously these functions
only took u32's, even with memory64 enabled. (#2506)
This PR also allows "software-bounds-checked" memories and "guard-page-checked"
memories to coexist in the same module. It creates two versions of every memory
operation: an unrestricted version (that works with any memory) and a _default32
version (for memories with default page size and i32 indexing). (#2507)
#2506 and #2507 have been squashed together to avoid a performance regression.
This is a stepping stone to supporting custom-page-sizes (which will need to be
software-bounds-checked) (#2508).
