void %test2(int*** %Q) {
  %P = load int*** %Q
  volatile store int** %P, int*** %Q

  int *l2_A;

  l2_A = (int **((volatile int **)l1_P));
  return;

  l1_P = *l2_Q;
  *((volatile int ***)l2_Q) = l1_P;
  return;
}

... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):

void test(int **l1_P) {
  int *l3_A;

  l3_A = *((int * volatile*)l1_P);

Make the check for global variables the same as the one for functions. In
both cases they are looking for non-external variables/functions that do
not have internal linkage. Using "!isExternal()" is a little more
understandable than "hasInitializer()"

Minor cleanup.  No need to explicitly tell the compiler the template arguments.

Make sure to clear the LazyFunctionLoadMap after we ParseAllFunctionBodies.
Otherwise, clients who call ParseAllFunctionBodies will attempt to parse
the function bodies twice, which is (uh) very very bad (tm).

This fixes gccld on python.

Do not put internal symbols into the symbol table.  This shrinks the symbol
table for archives in common cases, and prevents trying to resolve a
external reference with an internal reference.  This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

Fix PR506:
* Use error returned from Archive::OpenAndLoad
* Make sure only std::string is thrown so it gets caught and printed.

Correct the recursive PHI node handling routines in a way that CANNOT induce
infinite loops (using the new replaceSymbolicValuesWithConcrete method).

This patch reverts this patch:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050131/023830.html

... which was an attempted fix for this problem.  Unfortunately, that patch
caused test/Regression/Transforms/IndVarsSimplify/exit_value_tests.llx to fail
and slightly castrated the entire analysis.  This patch fixes it right.

This patch is dedicated to jeffc, for making me deal with this.  :)
