Finish instruction renaming

[aheejin]

This finishes #985. This

• replaces the old names in the tests with the new names
• drops support for the deprecated names
• renames test files to match new instruction names

I don't think dropping support for the old names will be a problem at
this point. #985 says the old names are supported for convenience but we
should remove those too at some point; that "some point" may have well
arrived given that three years have passed.

The lists of names updated are in #933, #1564, WebAssembly/spec#720.

@kripken @sbc100 This contains a renaming of wasm_rt_anyfunc_t -> wasm_rt_funcref_t in wasm2c. Would this make any problem for Emscripten? (I'm not sure if there's any syncing going on between Emscripten and Wabt, so I'm asking)

Renaming this without renaming all the other wasm_rt_anyfunc_t in wasm2c seems odd. wasm_rt_funcref_t doesn't seem to appear anywhere in wasm2c but I see several references to wasm_rt_anyfunc_t and a typedef for it.

Is this change needed for this PR? If not perhaps revert this file and create a seperate PR to change all the wasm_rt_anyfunc_t in wasm2c?

I also renamed it in wasm2c/wasm-rt.h. These two files are the only occurrence of wasm_rt_anyfunc_t in code in the current codebase. (Other than README.md) I also renamed that typedef:

--- a/wasm2c/wasm-rt.h
+++ b/wasm2c/wasm-rt.h

   WASM_RT_F64,

-typedef void (*wasm_rt_anyfunc_t)(void);
+typedef void (*wasm_rt_funcref_t)(void);

-  wasm_rt_anyfunc_t func;
+  wasm_rt_funcref_t func;
 } wasm_rt_elem_t;

But if this can be problematic I can split it to another PR. WDYT?

After running all tests, out/test/wasm2c directory seems to correctly contains files with wasm_rt_funcref_t:

aheejin@aheejin:~/wabt/out$ grep wasm_rt_funcref_t * -R
test/wasm2c/spec/func_ptrs/func_ptrs.9.c:  w2c_T0.data[offset + 0] = (wasm_rt_elem_t){func_types[0], (wasm_rt_funcref_t)(&w2c_f0)};
test/wasm2c/spec/func_ptrs/func_ptrs.9.c:  w2c_T0.data[offset + 1] = (wasm_rt_elem_t){func_types[0], (wasm_rt_funcref_t)(&w2c_f1)};
test/wasm2c/spec/func_ptrs/func_ptrs.8.c:  w2c_T0.data[offset + 0] = (wasm_rt_elem_t){func_types[0], (wasm_rt_funcref_t)(&w2c_f0)};
