First test case:
-enable-shrink-wrap=false

  # %bb.0:                        # %entry
  	pushq	%rax
  	movl	%edi, %eax
  	cmpl	%esi, %eax
  	jge	.LBB0_2
  # %bb.1:                        # %if.then
  	movl	%eax, 4(%rsp)
  	leaq	4(%rsp), %rsi
  	xorl	%edi, %edi
  	callq	_Z11doSomethingiPi
  .LBB0_2:                        # %if.end
  	popq	%rcx
  	retq

-enable-shrink-wrap=true

  # %bb.0:                        # %entry
  	movl	%edi, %eax
  	cmpl	%esi, %eax
  	jge	.LBB0_2
  # %bb.1:                        # %if.then
  	pushq	%rax
  	movl	%eax, 4(%rsp)
  	leaq	4(%rsp), %rsi
  	xorl	%edi, %edi
  	callq	_Z11doSomethingiPi
  	addq	$8, %rsp
  .LBB0_2:                        # %if.end
  	retq

The following instructions have changed and moved:

  'pushq	%rax'             move from %bb.0 to %bb.1
  'popq	%rcx'             changed into  'addq	$8, %rsp',
