237d9a105d stage2: support debug dumping zir as a build option 
So that it's not needed to manually comment and uncomment the debug
code.

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.

b498eebfd4 std.math.big: fix use-after-free 
When there is parameter aliasing, the ensureCapacity calls can cause the
Const parameters to become dangling pointers.

973e6c978c std: clean up GeneralPurposeAllocator memset code 
The freeSlot function was only called once so I inlined the logic and
utilized some of the other locals that were in scope.

These changes enable a Hello World example. However, all implemented
codegen is not yet feature-complete.

- asm only supports 'svc #0' at the moment
- call only supports leaf functions at the moment
- setReg uses a naive method at the moment
