Dan Gohman d5ae136971 Set the vim auto-indent setting for open braces after case statements to
follow LLVM source convention.

Before:
  case X: {
            stuff;
          }

After:
  case X: {

  }

David Chisnall 2c4a34aeef Fixed linking of modules containing aliases to constant bitcasts. Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).
Linking modules containing aliases to GEPs is still not quite right.  GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break.  Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later).

Benjamin Kramer f65e959035 Rework InitPreprocessor to use a MacroBuilder class instead of pushing around
std::vectors.

- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
  supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
  with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

Dan Gohman 6bd3ef82ff Revert an earlier change to SIGN_EXTEND_INREG for vectors. The VTSDNode
really does need to be a vector type, because
TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
and it needs to be able to distinguish between vectors and scalars.

Also, fix some more issues with legalization of vector casts.

Evan Cheng cc6d56bd3b Fix a critical bug in 64-bit atomic operation lowering for 32-bit. The results of the cmpxchg8b instructions are being thrown away when it branches back to the top of the checking loop. This means the loop always compares against the old value and this can result in a dead lock.

result int by 8 for the first byte.  While normally harmless,
if the result is smaller than a byte, this shift is invalid.

Ted Kremenek b92304b42f Fix handling in GRExprEngine of 'default' branch in switch statements
when the default case is winnowed down to be infeasible.  When all
cases were ruled out (and the analysis state for the default case
would be infeasible) we would still consider the default case
possible.  This fixes PR 5969.

Eric Christopher 7482ad7272 After further thought revert the patch to make fast-isel avoid
putting relocations into the constant pool - this isn't needed
for correctness and in the rare occasion it happens would pull
us out of fast isel for the block.

If fast-isel application startup time ever becomes an issue we
can add better support for these addresses instead of bailing.

John McCall 12f97bc48a Change the printing of OR_Deleted overload results to print all the candidates,
not just the viable ones.  This is reasonable because the most common use of
deleted functions is to exclude some implicit conversion during calls;  users
therefore will want to figure out why some other options were excluded.

Started sorting overload results.  Right now it just sorts by location in the
translation unit (after putting viable functions first), but we can do better than
that.

Changed bool OnlyViable parameter to PrintOverloadCandidates to an enum for better
self-documentation.

Douglas Gregor fa1e36d0de Improve the fix-its for -Wparentheses to ensure that the fix-it
suggestions follow recovery. Additionally, add a note to these
diagnostics which suggests a fix-it for changing the behavior to what
the user probably meant. Examples:

t.cpp:2:9: warning: & has lower precedence than ==; == will be evaluated first
      [-Wparentheses]
  if (i & j == k) {
        ^~~~~~~~
          (     )
t.cpp:2:9: note: place parentheses around the & expression to evaluate it first
  if (i & j == k) {
        ^
      (    )

t.cpp:14:9: warning: using the result of an assignment as a condition
