that this bug has been here for so long. Fixes <rdar://problem/10318778>.

[analyzer] Remove LocationContext creation methods from AnalysisManager, and change clients to use AnalysisContext instead.

able to constant fold load instructions where the argument is a constant.
Second, we should be able to watch multiple PHI nodes through the loop; this
patch only supports PHIs in loop headers, more can be done here.

With this patch, we now constant evaluate:
  static const int arr[] = {1, 2, 3, 4, 5};
  int test() {
    int sum = 0;
    for (int i = 0; i < 5; ++i) sum += arr[i];
    return sum;
  }

SHL inserts zeros from the right, thus even when the original
sign_extend_inreg value was of 1-bit, we need to sra.

Former RUN line does not make sense on Win32 hosts.
Win32 hosts would not be expected to set appropriate $PWD.

Latter RUN line might be made valid if PathV2::is_absolute("/foo") would be true. Unfortunately, "/foo" should not be treated as absolute path on Win32.

FYI, on mingw32 with MSYS bash (it has 'shell' feature);
Former) $PWD is set as "X:/hogehoge/test/Driver"
Latter) PWD=/foo sets "X:/root/to/msys/foo" to $PWD.

A patina of gdb's "display" command, intended mostly for simply monitoring

display/x $pc does not work.
