The key stored in the source map is a normalized path string with host's
path style, so it is also necessary to normalize the file path during
searching the map

Move DynamicRegisterInfo from the internal lldbPluginProcessUtility
library to the public lldbTarget library. This is a prerequisite
towards ABI plugin changes that are going to pass DynamicRegisterInfo
parameters.

Summary:
In our project we are using remote client-server LLDB configuration.
We want to parse as much debugging symbols as we can before debugger starts attachment to the remote process.
To do that we are passing the path of the local executable module to CreateTarget method at the client.
But, it seems that this method are not parsing the executable module symbols.
To fix this I added PreloadSymbols call for executable module to target creation method.
This patch also fixes a problem where the DynamicLoader would reset a
module when launching the target. We fix it by making sure
Platform::ResolveExecutable returns the module object obtained from the
remote platform.

Summary:
These definitions are used to "augment" information received from the remote
target with eh/debug frame and "generic" register numbers.
Besides being verbose, this information was also incomplete (new registers like
xmm16-31 were missing) and sometimes even downright wrong (ymm register
numbers).
Most of this information is available via llvm's MCRegisterInfo. This patch
creates a new class, MCBasedABI, which retrieves the eh and debug frame register
numbers this way. The tricky part here is that the llvm class uses all-caps
register names, whereas lldb register are lowercase, and sometimes called
slightly differently. Therefore this class introduces some hooks to allow a
subclass to customize the MC lookup. The subclass also needs to suply the
"generic" register numbers, as this is an lldb invention.
This patch ports the x86_64 ABI classes to use the new register info mechanism.
It also creates a new "ABIx86_64" class which can be used to house code common
to x86_64 both ABIs. Right now, this just consists of a single function, but
there are plenty of other things that could be moved here too.

One way to register a recognizer is to use RegularExpressionSP for the
module and symbol.
In order to match a symbol regardless of the module, the recognizer can
be registered with a nullptr for the module. However, this cause the
frame recognizer list command to crash because it calls
RegularExpression::GetText without checking if the shared pointer is valid.
This patch adds checks for the symbol and module RegularExpressionSP.

Currently ExecutionContext::GetByteOrder() always returns the host byte
order. This seems like a simple mistake: the return keyword appears to
have been omitted by accident. This patch fixes that and adds a unit
test.

Summary:
Instead of having SymbolVendor coordinate Symtab construction between
Symbol and Object files, make the SymbolVendor function a passthrough,
and put all of the logic into the SymbolFile.

Summary:
This creates an abstract base class called "UserIDResolver", which can
be implemented to provide user/group ID resolution capabilities for
various objects. Posix host implement a PosixUserIDResolver, which does
that using posix apis (getpwuid and friends). PlatformGDBRemote
forwards queries over the gdb-remote link, etc. ProcessInstanceInfo
class is refactored to make use of this interface instead of taking a
platform pointer as an argument. The base resolver class already
implements caching and thread-safety, so implementations don't have to
worry about that.
The main motivating factor for this was to remove external dependencies
from the ProcessInstanceInfo class (so it can be put next to
ProcessLaunchInfo and friends), but it has other benefits too:
- ability to test the user name caching code
- ability to test ProcessInstanceInfo dumping code
- consistent interface for user/group resolution between Platform and
Host classes.

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.

Summary:
Fetching an input file required about five lines of code, and this was
repeated in multiple unit tests, with slight variations. Add a helper
function for doing that into the lldbUtilityMocks module (which I rename
to lldbUtilityHelpers to commemorate the fact it includes more than
mocks)
