* Transform DWARF sections into native format for wasm2obj and wasmtime.
Generate DWARF sections based on WASM DWARF.
Ignore some of debug_info/debug_line for dead code.
* Fix test
wasmtime-execute is now wasmtime-jit. Move `JITCode` and the TargetIsa
into a new `Compiler` type. `InstancePlus` is no more, with trampoline
functionality now handled by `Compiler`.
And lots of other miscellaneous changes. Rename InstanceWorld to
InstancePlus and reorganize its contents. This still isn't a great name,
but at least now it has a clear purpose.
The memmap crate doesn't make it straightforward to have part of the
region be writeable and part readonly. Since this is a fairly boutique
use case, and we don't need all that much code, just use the low-level
APIs directly.
Also, introduce a concept of "tunables" for adjusting the parameters of
the runtime.
* Implement basics.
* Execute code
* Add wasm2wat test cases.
* abi_loc_for_arg for stack.
* Assert that sp_depth is 0 at the epilogue
* Do 32bit add.
* Assert that RAX can be used as a scratch register
* Reuse assembler.
* Align stack slots.
The biggest change is the split from FunctionIndex to
DefinedFuncIndex to FuncIndex. Take better advantage of this by
converting several Vecs to PrimaryMaps.
Also, table_addr can now handle indices of the table index type,
so we don't need to explicitly uextend them anymore.
