Cameron Zwarich 057fbb1a10 The element insertion code in scalar replacement doesn't handle incorrect 
element types, even though the element extraction code does. It is surprising
that this bug has been here for so long. Fixes <rdar://problem/10318778>.

Ted Kremenek 142adc492b [analyzer] Remove LocationContext creation methods from AnalysisManager, and change clients to use AnalysisContext instead. 
WIP to remove/reduce ExprEngine's usage of AnalysisManager.

Nick Lewycky a6674c7fc9 Make SCEV's brute force analysis stronger in two ways. Firstly, we should be 
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;
  }

sign_extend_inreg value was of 1-bit, we need to sra.

NAKAMURA Takumi 084e45bc37 test/Driver/debug.c: Mark this as "REQUIRES: shell". 
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.

Jason Molenda bc7748b7d3 Add "display" and "undisplay" aliases for target stop-hook add/delete. 
A patina of gdb's "display" command, intended mostly for simply monitoring
a variable as you step through source code.  Formatters do not work, e.g.
display/x $pc does not work.

Argyrios Kyrtzidis 6a59897d50 [PCH] When serializing Stmts, keep track of when sub statements are referenced again and 
in such a case just write out a reference of a previously serialized Stmt, instead
of serializing it all over again.

This saves memory + space + [de]serializing time, and avoids blowing up memory
with pathological cases. rdar://10293911
