This patch removes the logic for resolving paths out of FileSpec and
updates call sites to rely on the FileSystem class instead.

With the recent changes in FileSpec to use LLVM's path style, it is
possible to delegate a bunch of common path operations to LLVM's path
helpers. This means we only have to maintain a single implementation and
at the same time can benefit from the efforts made by the rest of the
LLVM community.
This is part one of a set of patches. There was no obvious way to split
this so I just worked from top to bottom.

When reading DBGSourcePathRemapping from a dSYM, we remove the last two
path components to make the source lookup more general. However, when
dealing with a relative path that has less than 2 components, we ended
up with an invalid (empty) FileSpec.
This patch changes the behavior of removeLastPathComponent to remove the
last path component, if possible. It does this by checking whether a
parent path exists, and if so using that as the new path. We rely
entirely on LLVM's path implementation to do the heavy lifting.
We now also return a boolean which indicates whether the operator was
successful or not.

PathMappingList was broken for relative and empty paths after normalization changes in FileSpec. There were also no tests for PathMappingList so I added those.
Changes include:
Change PathMappingList::ReverseRemapPath() to take FileSpec objects instead of ConstString. The only client of this was doing work to convert to and from ConstString objects for no reason.
Normalize all paths prefix and replacements that are added to the PathMappingList vector so they match the paths that have been already normalized in the debug info
Unify code in the two forms of PathMappingList::RemapPath() so only one contains the actual functionality. Prior to this, there were two versions of this code.
Use FileSpec::AppendPathComponent() and remove a long standing TODO so paths are correctly appended to each other.
Added tests for absolute, relative and empty paths.

After switching to LLVM normalization, if we init FileSpec with "." we would end up with m_directory being NULL and m_filename being "".
This patch fixes this by allowing the path to be normalized and if it normalized to nothing, set it to m_filename.

Summary:
The llvm version of the enum has the same enumerators, with stlightly
different names, so this is mostly just a search&replace exercise. One
concrete benefit of this is that we can remove the function for
converting between the two enums.
To avoid typing llvm::sys::path::Style::windows everywhere I import the
enum into the FileSpec class, so it can be referenced as
FileSpec::Style::windows.

Summary:
now that llvm supports host-agnostic path manipulation functions (and
most of their kinks have been ironed out), we can remove our copies of
the path parsing functions in favour of the llvm ones.
This should be NFC except for the slight difference in handling of the
"//" path, which is now normalized to "/" (this only applies to the
literal "//" path; "//net" and friends still get to keep the two
slashes).

Always normalizing lldb_private::FileSpec paths will help us get a consistent results from comparisons when setting breakpoints and when looking for source files. This also removes a lot of complexity from the comparison routines. Modified the DWARF line table parser to use the normalized compile unit directory if needed.
