Zachary Turner 1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

Jim Ingham 7ac5c86ba9 Fix the logic in DynamicLoaderMacOSXDYLD::Clear that would only remove the old dyld notification
breakpoint only  if the process it was for is still alive.  We need to always remove this because
it has a pointer to the old loader, and    if we ever hit it we will crash.  I also put in a sanity
check in the callback function to make sure we don't invoke it if the process is wrong.

* On Android (at least on platfrom-21 x86) the dynamic linker reports the
  executable with its full path
* Use the platform path of the executable when storing it into the cache
  (used to identify the SO entry for the executable) as this is the path
  what will be reported by the dynamic linker. If the platform path isn't
  set (local debugging) then it falls back to the normal file path.

Zachary Turner 32abc6edac Reduce header footprint of Target.h
This continues the effort to reduce header footprint and improve
build speed by removing clang and other unnecessary headers
from Target.h.  In one case, some headers were included solely
for the purpose of declaring a nested class in Target, which was
not needed by anybody outside the class.  In this case the
definition and implementation of the nested class were isolated
in the .cpp file so the header could be removed.

Combined, these patches reduce the build time of LLDB locally by
over 30%.  However, they touch many files and make many changes,
so will be submitted in small incremental pieces.

Greg Clayton 08928f308b Don't wait for the dynamic loader to set a module as a dynamic link editor, figure it out through the ObjectFile.
Background: dyld binaries often have extra symbols in their symbol table like "malloc" and "free" for the early bringup of dyld and we often don't want to set breakpoints in dynamic linker binaries. We also don't want to call the "malloc" or "free" function in dyld when a user writes an expression like "(void *)malloc(123)" so we need to avoid doing name lookups in dyld. We mark Modules as being dynamic link editors and this helps do correct lookups for breakpoints by name and function lookups.

Stephane Sezer 765fcc0d5b Use basename of main executable in POSIX-DYLD on Android.
Summary:
The Android dynamic linker reports only the basename of each SO entry, so for
the above check to be successful, we need to compare it to the basename of the
main executable.

This also has a nasty side-effect when working with older version of
Android (verified on platform version 16), and debugging PIE
executables: the dynamic linker has a bug and reports the load address
of the main executable (which is a shared object, because PIE) to be 0.
We then try to update the list of loaded sections for all shared
objects, including the main executable, and set the load address to 0,
which breaks everything that relies on resolving addresses in the main
executable (breakpoints, stepping, etc). This commit also fixes that broken
behavior when debugging on older Androids. This bug doesn't happen on newer
Android versions (verified for Android L).

Test Plan: Run test suite on linux.

Justin Hibbits 6256a0ea8f First cut of PowerPC(64) support in LLDB.
Summary:
This adds preliminary support for PowerPC/PowerPC64, for FreeBSD.  There are
some issues still:

 * Breakpoints don't work well on powerpc64.
 * Shared libraries don't yet get loaded for a 32-bit process on powerpc64 host.
 * Backtraces don't work.  This is due to PowerPC ABI using a backchain pointer
   in memory, instead of a dedicated frame pointer register for the backchain.
 * Breakpoints on functions without debug info may not work correctly for 32-bit
   powerpc.

Todd Fiala 952bccd212 POSIX dynamic loader: add more logging around launch/attach, fix breakpoint handling on entry callback.
This change adds some logging around dynamic loader handling.
It also fixes an issue where the dynamic loader entry breakpoint can end
up being re-inserted, showing the wrong (i.e. software breakpoint) instruction
at the stop location when a backtrace is displayed at program startup.

I discussed with Jim Ingham a few weeks back.  Essentially the
one-hit breakpoints need to make it back to public state handling before
the software breakpoint gets cleared.  The flow I was hitting was that
the breakpoint would get set, it would get hit, it would get cleared to
step over, then it would get reapplied, when we never wanted it reapplied.
Stops at the beginning of execution would then show backtraces with
software breakpoint instructions in it, erroneously.  This change fixes it.
There might be a more elegant way to do this, or a flow change somewhere else
to avoid, but it does fix an issue I experienced in startup breakpoint handling.

unloaded when we finished handling the first real load event.  Add its sections.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.

Not every debugserver option is covered yet.  Currently
