Consider these two consecutive runs of HowToUseJIT on ARM: one returns 11
(correct) the other returns 10 (wrong).  It fails on about 1 of 4 runs.
tested using rev 81338

We just constructed this LLVM module:

; ModuleID = 'test'

define i32 @add1(i32 %AnArg) {
EntryBlock:
  %addresult = add i32 1, %AnArg                  ; <i32> [#uses=1]
  ret i32 %addresult
}

define i32 @foo() {
EntryBlock:
  %add1 = tail call i32 @add1(i32 10)             ; <i32> [#uses=1]
  ret i32 %add1
}

declare void @abort()


Running foo: Result: 11
