Summary:
All the tests pass without hitting the situation mentioned in the FIXME, so,
per Aaron Smith's suggestion, this case will now return unconditionally.

Summary:
This is combination of following changes,
- Resolve function symbols in PDB symbol file. `lldb-test symbols` will display information about function symbols.
- Implement SymbolFilePDB::FindFunctions methods. On lldb console, searching function symbol by name and by regular expression are both available.
- Create lldb type for PDBSymbolFunc.
- Add tests to check whether functions with the same name but from different sources can be resolved correctly.

`num_args` is unsigned integer, declared as below:
```
uint32_t num_args = arg_enum->getChildCount();
```
Comparison with the signed `arg_idx` produces a warning when compiled with
-Wsign-compare flag, this patch addresses this simple issue without affecting
any functionality.

Summary:
- Fix a null array access bug. This happens when creating the lldb type for a function that has no argument.
- Implement SymbolFilePDB::ParseTypes method. Using `lldb-test symbols` will show all supported types in the target.
- Create lldb types for variadic function, PDBSymbolTypePointer, PDBSymbolTypeBuiltin
- The underlying builtin type for PDBSymbolTypeEnum is always `Int`, correct it with the very first enumerator's encoding if any. This is more accurate when the underlying type is not signed or another integer type.
- Fix a bug when the compiler type is not created based on PDB_BuiltinType. For example, basic type `long` is of same width as `int` in a 32-bit target, and the compiler type of former one will be represented by the one generated for latter if using the default method. Introduce a static function GetBuiltinTypeForPDBEncodingAndBitSize to correct this issue.
- Basic type `long double` and `double` have the same bit size in MSVC and there is no information in a PDB to distinguish them. The compiler type of the former one is represented by the latter's.
- There is no line information about typedef, enum etc in a PDB and the source and line information for them are not shown.
- There is no information about scoped enumeration. The compiler type is represented as an unscoped one.

llvm-svn: 322995
Summary:
This commit is a combination of the following changes:
- Cache PDB's global scope (executable) in SymbolFilePDB
- Change naming of `cu` to `compiland` which is PDB specific
- Change ParseCompileUnitForSymIndex to ParseCompileUnitForUID.
Prefer using a common name `UID` instead of PDB's `System Index`
Adding one more argument `index` to this method, which is used to
specify the index of the compile unit in a cached compile unit array
- Add GetPDBCompilandByUID method to simply code
- Fix a bug in getting the source file name for a PDB compiland.
For some reason, PDBSymbolCompiland::getSourceFileName() could
return an empty name, so if that is true, we have to walk through all
source files of this compiland and determine the right source file
used to generate this compiland based on language indicated.
The previous implementation called PDBSession::findOneSourceFile
method to get its name for the compiland. This is not accurate since
the `one source file` found could be a header other than source file.

Summary:
It was possible when searching for a symbol by regex in a pdb that an invalid regex would cause an exception on Windows. This updates the code to avoid throwing an exception.
When fixing the exception it was decided there is no reason to search for a symbol in a pdb by regex. To support this, SymbolFilePDB::FindTypes() now only searches for types by name and no longer calls FindTypesByRegEx().

A clang change caused the inclusion of `llvm::Type` and
`lldb_private::Type` to be pulled into the global namespace due to the
`using namespace llvm;` and `using namespace lldb_private;`. Explicitly
qualify the `Type` to resolve the ambiguity. NFC

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

This implements a PDBASTParser and corresponding logic in
SymbolFilePDB to do type lookup by name. This is just a first
pass and leaves many aspects of type lookup unimplemented, and
just focuses on laying the framework. With this patch, you should
be able to lookup basic types by name from a PDB.
Full class definitions are not completed yet, we will instead
just return a forward declaration of the class.
