Benjamin Kramer 95c7c427aa Add printName to DeclarationName which prints the human-readable name on a
raw_ostream. Use it in getAsString and NamedDecl's raw_ostream operator.

Benjamin Kramer b11416d061 Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.
The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Eric Christopher 8d0c621ca6 Consolidate most of the integer constant expression builtin requirement
checking into a single function and use that throughout. Remove some
now unnecessary diagnostics and update tests with now more accurate
diagnostics.

Chris Lattner 4ebae65d6a make our existing "switch on bool" warning work for C. Since
the result of comparisons are 'int' in C, it doesn't work to
test just the result type of the expression.

Douglas Gregor b2ccf010fb Feed proper source-location information into Sema::LookupSingleResult,
in case it ends up doing something that might trigger diagnostics
(template instantiation, ambiguity reporting, access
reporting). Noticed while working on PR6831.

Daniel Dunbar 3d9289c736 Add TargetInfo::useBitfieldTypeAlignment().
- Used to determine whether the alignment of the type in a bit-field is
   respected when laying out structures. The default is true, targets can
   override this as needed.

 - This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in
   gcc. The AST/Sema implementation only affects one line, unless I have
   forgotten something. I'd appreciate further review.

 - IRgen still needs to be updated to fully support this (which is effectively
   PR5591).

Daniel Dunbar 76fa840d09 Driver/Frontend: Add support for -mllvm, which forwards options to the LLVM option parser.
- Note that this is a behavior change, previously -mllvm at the driver level forwarded to clang -cc1. The driver does a little magic to make sure that '-mllvm -disable-llvm-optzns' works correctly, but other users will need to be updated to use -Xclang.

Eric Christopher 1bbc7086ff Rewrite handling of 64-bit palignr intrinsics to be vector shuffles.
Stop multiplying constant by 8 accordingly in the header and change
intrinsic definition for what types we expect.

Douglas Gregor 064fdb2fe8 Always diagnose and complain about problems in
ResolveAddressOfOverloadedFunction when asked to complain. Previously,
we had some weird handshake where ResolveAddressOfOverloadedFunction
expected its caller to handle some of the diagnostics but not others,
and yet there was no way for the caller to know which case we were
in. Eliminate this madness, fixing <rdar://problem/7765884>.

Douglas Gregor 2d2d90750c Once we've emitted a fatal diagnostic, keep counting errors but with a
separate count of "suppressed" errors. This way, semantic analysis
bits that depend on the error count to determine whether problems
occured (e.g., some template argument deduction failures, jump-scope
checking) will not get confused.

The actual problem here is that a missing #include (which is a fatal
error) could cause the jump-scope checker to run on invalid code,
which it is not prepared to do. Trivial fix for both
<rdar://problem/7775941> and <rdar://problem/7775709>.

Douglas Gregor 2bf2d3d016 When diagnosing suspicious precedence or assignments, move the fix-it
that adds parentheses from the main diagnostic down to a new
note. This way, when the fix-it represents a choice between two
options, each of the options is associted with a note. There is no
default option in such cases. For example:

/Users/dgregor/t.c:2:9: warning: & has lower precedence than ==; ==
will be
      evaluated first [-Wparentheses]
  if (x & y == 0) {
        ^~~~~~~~
/Users/dgregor/t.c:2:9: note: place parentheses around the &
expression to
      evaluate it first
  if (x & y == 0) {
        ^
      (    )
/Users/dgregor/t.c:2:9: note: place parentheses around the ==
expression to
      silence this warning
  if (x & y == 0) {
        ^
          (     )

Douglas Gregor 8aa4ebf0bc Implement typo correction for Objective-C message sends when the
receiver is a mis-typed class name. Previously, we would give a non-specific
typo-correction diagnostic from the expression-parsing code, but there
was no fix-it because it was too late to recover. Now, we give a nice
diagnostic

honk.m:6:4: error: unknown receiver 'Hnk'; did you mean 'Honk'?
  [Hnk method];
   ^~~
   Honk
honk.m:1:1: note: 'Honk' declared here
@interface Honk
^

which includes a fix-it.

We still need to recover better from mis-typing "super".

Douglas Gregor a148a1d40e Introduce a parsing action to distinguish between class, instance, and
super message sends in Objective-C. No actual functionality change
here, but it provides a hook so that Sema can typo-correct the

Ted Kremenek ac034616f1 Use ASTVector instead of std::vector for the Exprs in InitListExpr. Performance

Ted Kremenek a98e8aa15d Introduce ASTVector, which is a std::vector-like class that allocates all memory

Chris Lattner a36ec4243b fix PR6811 by not parsing 'super' as a magic expression in
LookupInObjCMethod.  Doing so allows all sorts of invalid code
to slip through to codegen.  This patch does not change the 
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.

There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.
