The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

Summary:
various platforms very using nearly identical code for this method. As far as I
can tell there was nothing platform-specific about the differences, but rather
it looked like it was caused by tiny tweaks being made to individual copies
without affecting the overall functionality. I have taken the superset of all
these tweaks and put it into one method in the base class (incidentaly, nobody
was using the base class implementation of the method, as all classes were
overriding it). From the darwin class I took the slightly improved error
reporting (checking whether the file is readable) and the
ResolveExecutableInBundle call (which has no effect elsewhere as the function
is already a no-op on non-darwin platforms). From the linux class I took the
set-the-triple-vendor-to-host-if-unspecified tweak (present in PlatformKalimba
as well).
PlatformWindows has an identical copy as well. We could resolve that by pushing
this code further down into Platform class, that that would require pushing the
m_remote_platform_sp member as well, which seems like a bad design choice.

which will be installed versioned (with a non-versioned symlink). This

Mac OS X 10.11, El Capitan, released c. Oct 2015) I conditionalized
the use of the framework on "if sdk == macosx 10.11". But since
macOS 10.12 has shipped this year, the framework was no longer being
built in. I can either start listing every OS 10.11 and newer, or
remove the version check.
This will break building lldb with xcodebuild / Xcode for people
running Mac OS X 10.10 or older. If so, I'll back this change out.
I'm not sure if we have many people working on macs running the
older OSes on their build systems.

llvm-svn: 293742
Summary:
Problem:
There are three filelds in the ELF header - e_phnum, e_shnum, and e_shstrndx -
that could be bigger than 64K and therefore do not fit in 16 bits reserved for
them in the header. If this happens, pretty often there is a special section at
index 0 which contains their real values for these fields in the section header
in the fields sh_info, sh_size, and sh_link respectively.
Fix:
- Rename original fields in the header declaration. We want to have them around
just in case.
- Reintroduce these fields as 32-bit members at the end of the header. By default
they are initialized from the header in Parse() method.
- In Parse(), detect the situation when the header might have been extended into
section info #0 and try to read it from the same data source.
- ObjectFileELF::GetModuleSpecifications accesses some of these fields but the
original parse uses too small data source. Re-parse the header if necessary
using bigger data source.
- ProcessElfCore::CreateInstance uses header with potentially sentinel values,
but it does not access these fields, so a comment here is enough.

Summary:
This patch does two things. First it updates all the ABI plugins with accurate dependencies, and second it adds a tracking mechanism for add_lldb_library to denote plugin libraries, allowing us to build up a list of all the configured plugins.
This list of generated plugins will be used during generating liblldb so that we can link all the plugins into the library.
If this patch looks good I will update all the other plugins in subsequent patches.

This change reverts the lldb-server part of r293686, which is having trouble on Linux bots. I'm not sure if I can make lldb-server work correctly until the full dependency graph is fixed.
llvm-svn: 293690
Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.
In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.
For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

lbound = 0x..., ubound = 0x..., (pointer value = 0x..., metadata = 0x...)

header line, backtrace output) was to remove the current pc value
from frames where we have source level information. We've been
discussing this for the past week and based on input from a group
of low level users, I believe this is the wrong default behavior
for the command line lldb tool.
lldb's backtrace will include the pc value for all stack frames
regardless of whether they have source level debug information or
not.
A related part of r286288 removes the byte offset printing for
functions with source level information (e.g. "main + 22 sourcefile.c:10"
is printed as "main sourcefile.c:10"). I don't see a compelling
case for changing this part of 286288 so I'm leaving that as-is
(in addition to the rest of 286288 which is clearly better than
the previous output style).
