Add support to share llvm fields for bit-fields.
For example, struct { char a; short b:2; };

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44830 91177308-0d34-0410-b5e6-96231b3b80d8

Explicitly set the string literal type from "char *" to "constant array of char".

At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44823 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed bug in CFG::PopulateBlkExprMap where the ordering
between fetching the size of the expression map (for use as
the next integer id for an Expr*) and the creation of the
entry in the map could be non-deterministic.  This could
cause the size of the map to be incremented prior to the
index being determine.

On Linux the map entry would be created first, causing the
map to the "size" to be incremented prior to it being
queried. On Mac OS X we had the reverse behavior. Now the
size is always queried prior to the new id being inserted
into the map.

This was the real cause of the bit-overrun triggered in
PR 1847:

  http://llvm.org/bugs/show_bug.cgi?id=1847

Also reverted the change in patch 44813, which was a bogus

Fix a pretty big but subtle bug counting the number of newlines to emit.
This would cause us to emit different code (in -E mode) for these two files:

---
#define t(x) x

t(a
3)
---
#define t(x) x
t(a
3)
---

In one case, -E would print "a\n3", in the other it printed "a3".  Now
it prints "a3" for both.

On Steve's suggestion, moved handling of use of undeclared method in a message
to rewriter (my previous patch).

More struct bitfields layout work. Now handle,

struct STestB1 {char a; char b:2; } stb1;
struct STestB2 {char a; char b:5; char c:4} stb2;

Fix a bug handling typedefs of functions, patch by Nuno Lopes!

A missing method in a messaging expression issues a warning, clients must not
crash because of this.

Subdivided the function InitializeBaseLanguage into InitializeBaseLanguage,
GetLanguage, and InitializeLangOptions.  The goal is to break up this logic
into atomic units of functionality that can later be refactored into better
driver logic that is capable of handling a mixture of source files of
different languages.

Avoid passing Diags into InitializeIncludePaths.

Make sure Parser::ParseObjCSelectorExpression() handles unary selectors (with no arguments) properly.

Removed dependence on including iostream (use llvm/Support/Streams.h instead).

Converted SerializationTest (--test-pickling) to use the new TranslationUnit
class to serialize and deserialize translation units.

Make sure the class methods get attached to the metaclass object.
Need to query the implementation, not the interface...

Added Driver/TranslationUnit.h and Driver/TranslationUnit.cpp to the
XCode project.

Added "TranslationUnit" class that will be used to provide an interface
for serializing/deserializing ASTs that is decoupled from the logic
in SerializationTest (which will soon be rewritten to use this interface).

Modified: CreateTargetInfo().  Now takes Diagnostic* instead of Diagnostic&.
Modified: ctor of SerializationTest: Now takes LangOptions argument.  We
          will eventually serialize this as well.

I'm apparently the only sad lonely ppc user left :)

Moved creation of ASTConsumers that can operate on both freshly-parsed and
deserialized ASTs into the function CreateASTConsumer().  This function
is called by ProcessInputFile, and soon the logic that processes deserialized
ASTs.

Implement CodeGen for vectors. Don't create unnecessary conversion instructions if the value to be converted is a constant.
