dc7608da97 ensure main return type is not i8 
Avoids a compile error from start.zig:

	/home/kivikakk/zig/build/lib/zig/std/start.zig:265:28: error:
	expected type 'u8', found 'i8'
			    return result;
				   ^
	/home/kivikakk/zig/build/lib/zig/std/start.zig:265:28: note:
	unsigned 8-bit int cannot represent all possible signed 8-bit
	values
			    return result;

fc001110b4 Added edge case test to mem.count 
Some implementations break on this edge case. Thought relevant to add it.

b8729ca1a0 Improve crypto benchmarks 
- 1MiB objects on the stack doesn't play well with wasmtime.
Reduce these to 512KiB so that the webassembly benchmarks can run.
- Pass expected results to a blackBox() function. Without this, in
release-fast mode, the compiler could detected unused return values,
and would produce results that didn't make sense for siphash.
- Add AEAD constructions to the benchmarks.
- Inline chacha20Core() makes it 4 times faster.
- benchmarkSignatures() -> benchmarkSignature() for consistency.

e97157f71c stage2: codegen for conditional branching 
* Move branch-local register and stack allocation metadata to the
   function-local struct. Conditional branches clone this data in order
   to restore it after generating machine code for a branch.
   Branch-local data is now only the instruction table mapping *ir.Inst
   to MCValue.
 * Implement conditional branching
   - Process operand deaths
   - Handle register and stack allocation metadata
 * Avoid storing unreferenced or void typed instructions into
   the branch-local instruction table.
 * Fix integer types reporting the wrong value for hasCodeGenBits.
 * Remove the codegen optimization for eliding length-0 jumps. I need to
   reexamine how this works because it was causing invalid jumps to be
   emitted.

Hardcode runtime (libSystem) version to minimum possible 
While we try to work out what the correlation between the OS and runtime
versions is, this commit hardcodes the latter to the minimum (compat)
version of 1.0.0.
