-airLoad and airStore now properly report an error if they are used with an array, instead of having the C compiler emit a vague error
-airStoreUndefined now works with array types
-structFieldPtr now works with array types, allowing generics' tests to pass
-add additional test cases that were found to be passing
-add basic int128 test cases which previously did not pass but weren't covered
-most test cases in cast.zig now pass
-i128/u128 or smaller int constants can now be rendered
-unsigned int constants are now always suffixed with 'u' to prevent random compile errors
-pointers with a val tag of 'zero' now just emit a 0 constant which coerces to the pointer type and fixes some warnings with ordered comparisons
-pointers with a val tag of 'one' are now casted back to the pointer type
-support pointers with a u64 val
-fix bug where rendering an array's type will emit more indirection than is needed
-render uint128_t/int128_t manually when needed
-implement ptr_add/sub AIR handlers manually so they manually cast to int types which avoids UB if the result or ptr operand is NULL
-implement airPtrElemVal/Ptr
-airAlloc for arrays will not allocate a ref as the local for the array is already a reference/pointer to the array itself
-fix airPtrToInt by casting to the int type
A new print field is added to RunStep that will control whether it prints the cmd before running it. By default it will be set to builder.verbose which means it will print only if builder.verbose is true.
The stack has been adjusted so that instead of pushing to index 0 in the
integer we push to the current end/index of the underlying integer. This
means we don't require a shift for every limb after each push/pop and
instead only require a mask/or and add/sub on a single element of the array.
Fixes#5959.
This test can fail due to a fix in musl for 32 bit MIPS, where musl changes limits greater than -1UL/2 to RLIM_INFINITY.
See http://git.musl-libc.org/cgit/musl/commit/src/misc/getrlimit.c?id=8258014fd1e34e942a549c88c7e022a00445c352
Depending on the system where the test is run getrlimit can return
RLIM_INFINITY for example if RLIMIT_MEMLOCK is bigger than ~2GiB.
If that happens, the setrlimit call will fail with PermissionDenied.
The symbol "_tls_index" gets lost when using LTO.
Disabling LTO on the object file that defines it allows the link to work.

* wasm: Move wasm's codegen to arch/wasm/CodeGen.zig
* wasm: Define Wasm's Mir
This declares the initial most-used instructions for wasm as
well as the data that represents them.
TODO: Add binary operand opcodes.
By re-using the wasm opcode values, we can emit each opcode very easily
by simply using `@enumToInt()`. However, this poses a possible problem:
If we use all of wasm's opcodes, it leaves us no room to use synthetic opcodes such as debugging instructions.
We could use reserved opcodes, but the wasm spec may use them at some point.
TODO: Check if we should perhaps use a 16bit tag where the highest bits are used for synthetic opcodes.
* wasm: Define basic Emit structure
* wasm: Implement corresponding Emit functions for MIR
* wasm: Initial lowering to MIR
- This implements lowering to MIR from AIR for storing and loading of locals
as well as emitting immediates.
- Relocating function indexes has been simplified a lot as well as we no
longer need to patch offsets and we write a relocatable value instead.
- Locals are now emitted at the beginning of the function section entry
meaning all offsets we generate are stable.
* wasm: Lower all AIR instructions to MIR
* wasm: Implement remaining MIR instructions
* wasm: Fix function relocations
* wasm: Get all tests working
* wasm: Make `Data` 4 bytes instead of 8.
- 64bit immediates are now stored in 2 seperate u32's.
- 64bit floats are now stored in 2 seperate u32's.
- `mem_arg` is now stored as a seperate payload in extra.
* add team_info, area_info
* update signature for get_next_image_info
* add error checks for haiku system calls
* update and cleanup of haiku constants
This commit makes airStore() handle undefined values directly instead of
delegating to renderValue(): the call to renderValue() happens too late,
when "dest = " has already been written to the stream, at which point
there's no sane way to initialize e.g. struct values by assignment.
Instead, we make airStore() use memset(dest, 0xaa, sizeof(dest)), which
should transparently handle all types.
Also moves the newly-passing tests to the top of test/behavior.zig.
