Douglas Gregor 6fd55e06d3 Teach ASTUnit to hold on to the Sema object and ASTConsumer that are
used when parsing (or re-parsing) a file. Also, when loading a
precompiled header into ASTUnit, create a Sema object that holds onto
semantic-analysis information.

Daniel Dunbar fa6214c952 Frontend: Rename hasASTSupport to hasASTFileSupport, which is more accurate.

Douglas Gregor 7f95d26e53 Make Diagnostic reference-counted, which is simpler than juggling
maybe-ownership vs. ownership.

Douglas Gregor d03e823fb4 Clarify the ownership semantics of the Diagnostic object used by
ASTUnit. Previously, we would end up with use-after-free errors
because the Diagnostic object would be creating in one place (say,
CIndex) and its ownership would not be transferred into the
ASTUnit. Fixes <rdar://problem/7818608>.

Douglas Gregor 522e22d352 Tell ASTMerge to merge every declaration it sees, rather than cherry-picking those declarations that we know will work.

Douglas Gregor 7eeb59752a When AST merging for record declarations fails, warn about the
incompatibility and show where the structural differences are. For
example:

struct1.c:36:8: warning: type 'struct S7' has incompatible definitions
in different translation units
struct S7 { int i : 8; unsigned j : 8; } x7;
       ^
struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here
struct S7 { int i : 8; unsigned j : 8; } x7;
                                ^
struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here
struct S7 { int i : 8; unsigned j : 16; } x7;
                                ^

There are a few changes to make this work:
  - ASTImporter now has only a single Diagnostic object, not multiple
  diagnostic objects. Otherwise, having a warning/error printed via
  one Diagnostic and its note printed on the other Diagnostic could
  cause the note to be suppressed.
  - Implemented import functionality for IntegerLiteral (along with
  general support for statements and expressions)

Douglas Gregor bb7930c17e Implement basic support for merging function declarations across
translation units.

Douglas Gregor 2fbe558cfe Teach AST merging that variables with incomplete array types can be
merged with variables of constant array types. Also, make sure that we
call DiagnosticClient's BeginSourceFile/EndSourceFile, so that it has
a LangOptions to work with.

Douglas Gregor 811663eb11 Implement basic support for importing source locations from one AST
into another AST, including their include history. Here's an example
error that involves a conflict merging a variable with different types
in two translation units (diagnosed in the third AST context into
which everything is merged).

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5:
error: external variable 'x2' declared with incompatible types in
different translation units ('int' vs. 'double')
int x2;
    ^

/Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.h:1:8:
note: declared here with type 'double'
double x2;
       ^

Although we maintain include history, we do not maintain macro
instantiation history across a merge. Instead, we map down to the
spelling location (for now!).

Douglas Gregor 6b2a474531 Hook up the diagnostics-argument printer when merging AST files, so
that we get readable diagnostics such as:

error: external variable 'x1' declared with incompatible types in
different translation units ('double *' vs. 'float **')

However, there is no translation of source locations, yet.

Douglas Gregor 62d311fdf4 Introduce a testbed for merging multiple ASTs into a single AST
context with the AST importer. WIP, still useless but at least it has
a test.
