[Bug tree-optimization/24888] New: duplication of local variables after versioning/inlining

[razya at il dot ibm dot com]

For the testcase:
/home/razya/mainline_new_3/gcc/gcc/testsuite/gcc.c-torture/execute/20021111-1.c,
when using fipa-cp, a new vfersion is created
for aim_callhandler(). the static variable is copied twice into the
unexpanded_var_list of the versioned function. 
Looking at this test, even without enabling ipa-cp, the local variables
multiplies after inlining.(as shown in the dump below)
For example :
in 20021111-1.c.t23.alias1:

aim_callhandler (sess, conn, family, type)
{
  int D.1449;
  int sess;
  int conn;
  short unsigned int family;
  short unsigned int type;
  static int i = 0;
  int D.1457;
  int D.1456;
  int i.0;
  int D.1458;
  int D.1449;
  int D.1435;
  int sess;
  int conn;
  short unsigned int family;
  short unsigned int type;
  static int i = 0;
  int D.1443;
  int D.1442;
  int i.0;
  int D.1444;
  int D.1435;
  int D.1421;
  int sess;
  int conn;
  short unsigned int family;
  short unsigned int type;
  static int i = 0;
  int D.1429;
  int D.1428;
  int i.0;
  int D.1430;
  int D.1421;
  int D.1407;
  int sess;
  int conn;
  short unsigned int family;
  short unsigned int type;
  static int i = 0;
  int D.1415;
  int D.1414;
  int i.0;
