Aaron Smith 10a02577ea [lldb] Add support to cache a PDB's global scope and fix a bug in getting the source file name for a compiland
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.

Aaron Smith 364cbfe964 Update failing PDB unit tests that are searching for symbols by regex
Summary: D41086 fixed an exception in FindTypes()/FindTypesByRegex() and caused two lldb unit test to fail. This change updates the unit tests to pass again.

Aaron Smith 86e9434db9 [lldb] Stop searching for a symbol in a pdb by regex
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().

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** 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.

Zachary Turner 54fd7ff6db Update for llvm change to add pdb namespace.
r268544 moves all PDB reading code into a pdb namespace,
so LLDB needs to be updated to take this into account.

Zachary Turner 42dff79068 Initial support for reading type information from PDBs.
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.

Zachary Turner 74e08ca05c Add support for reading line tables from PDB files.
PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.

Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows.  This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.

This patch only adds support for line tables.  It does not return
information about functions, types, global variables, or anything
else.  This functionality will be added in a followup patch.
