Initial port of top-level code generator to ARM.  For the constant
true at the top level we generate:

  0  stmdb sp!, {r1, r8, fp, lr}
  4  add fp, sp, #8
  8  ldr ip, [r10, #+4]
 12  ldr r2, [r10, #+0]
 16  str ip, [sp, #-4]!
 20  add lr, pc, #4
 24  cmp sp, r2
 28  ldrcc pc, [pc, #+68]        ;; code: STUB, StackCheck, minor: 0
 32  ldr ip, [pc, #+68]          ;; object: 0xf5bc4161 <true>
 36  str ip, [sp, #-4]!
 40  ldr ip, [sp, #+0]
 44  str ip, [fp, #-12]
 48  add sp, sp, #4
 52  ldr ip, [fp, #-12]
 56  str ip, [sp, #-4]!
 60  ldr r0, [sp], #+4
 64  mov sp, fp                  ;; js return
 68  ldmia sp!, {fp, lr}
 72  add sp, sp, #4
 76  bx lr
 80  ldr r0, [r10, #+4]
 84  mov sp, fp                  ;; js return
 88  ldmia sp!, {fp, lr}
 92  add sp, sp, #4
 96  bx lr
100  constant pool begin
104  constant
108  constant

I know 'the return address on top of them' is wrong.  Will fix before
committing.
