It looks like that we correctly track liveliness by
Live on entry to BB2 :
Live on entry to BB3 : a_lsm.27_5
Live on entry to BB4 : a_lsm.27_5
Live on entry to BB5 :
Live on entry to BB6 :

Somewhat shorter:
extern void abort (void);
unsigned int a, b = 1, c;
void __attribute__ ((noinline))
foo (int x)

if (x != 5)

Testcase failing with -O3 but not with -O3 -fno-unswitch-loops:
extern void abort (void);
unsigned int g_24;
unsigned int g_37 = 1;
unsigned int g_225 = 0;
void __attribute__((noinline)) foo (int x)
{
if (x != 5

-fno-unswitch-loops fixes the original testcase but not the following which
only fails _with_ -O3 -fno-unswitch-loops.
extern void abort (void);
unsigned int g_24;
unsigned int g_37 = 1;
unsigned int g_225 = 0;
