bf72146607 Fix volatile load/store of pointers. Consider this testcase: 
void %test(int** %P) {
  %A = volatile load int** %P
  ret void
}

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

instead of emitting:

void test(int **l1_P) {
  int *l2_A;

  l2_A = (int **((volatile int **)l1_P));
  return;
}
void test2(int ***l2_Q) {
  int **l1_P;

  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);
  return;
}
void test2(int ***l2_Q) {
  int **l1_P;

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

fcfc76189d For PR496: 
When llvm-gcc is not available, bypass rules for Modules and Bytecode
Libraries that require llvm-gcc and emit instead a warning that llvm-gcc
is not available. This permits "make LLVMGCC=" to build LLVM completely
without error and provides warnings about the modules and bc libs that
could not be constructed.

43b14db4d9 Print GEP offsets as signed values instead of unsigned values. On X86, this 
prints:

getelementptr (int* %A, int -1)

as: "(A) - 4" instead of "(A) + 18446744073709551612", which makes the
assembler much happier.

This fixes test/Regression/CodeGen/X86/2005-02-14-IllegalAssembler.ll,
and Benchmarks/Prolangs-C/cdecl with LLC on X86.

a7a01f13df 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()"

1788cf35ab 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.

fdc746ac38 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.

63d47e902f 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.  :)
