Someone must have changed the behavior of FileSpec slightly
relating to whether or not there is a trailing backslash when calling
GetPath() and GetDirectory(). This caused ScriptInterpreterPython
to find the wrong values when initializing sys.path, and as a result
we couldn't find the lldb module.
This patch fixes the issue, and also adds a test to make sure that
GetDirectory() does not return a string containing a trailing slash.

There were two versions of DoAttachToprocessWithId. One that takes
a pid_t, and the other which takes a pid_t and a ProcessAttachInfo.
There were no callers of the former version, and all of the
implementations of this version were simply forwarding calls to
one version or the other.

Summary:
This was originally http://reviews.llvm.org/D8709 , but I didn't commit it correctly.
Since then GetSupportedArchitectureAtIndex() has been changed. That change, http://reviews.llvm.org/D9511 , breaks non-x86 linux implementations, so this change goes back to the old implementation and adds remote linux support from D8709.
D8709 summary:
The Linux Platform currently will only say the Host architecture is supported. This patch retains that behavior for the Host Platform, but adds a list of architectures for the Remote Platform.

-dump mode normally omits blob data that contains unprintable characters.
When -show-binary-blobs is passed, it unilaterally escapes all blobs,
allowing those with binary data to be displayed.

Checks the host platform to determine logging channel to test in
TestRegisters.py as the logging runs host side.
Test Plan:
./dotest.py $DOTEST_OPTS -v -t -p TestRegisters.py
This passes mac -> linux as it's logging the correct channel.

We require a workaround to be able to locate global and anonymous namespace
functions in the dwarf symbols on linux binaries. This patch enables this code
on all platforms so that we can still find these symbols when debugging from a
different host platform.
Test Plan:
The following tests begin passing when running with a mac host to linux client:
TestCallCPPFunction.py
TestCallStopAndContinue.py
TestExprs.py
TestExprsChar.py
TestNamespace.py
TestOverloadedFunctions.py
TestRvalueReferences.py

This patch uses the new function profile metadata "function_entry_count"
to annotate entry counts from sample profiles.
In a sampling profile, the total samples collected at the function entry
are an approximation for the number of times that function was invoked.

before binary/ternary operators.
Basically, it doesn't seem right to indent a nested block aligned to a
binary or ternary operator.
Before:
int i = aaaaaa ? 1 //
: [] {
return 2; //
}();
llvm::errs() << "number of twos is "
<< std::count_if(v.begin(), v.end(), [](int x) {
return x == 2; // force break
});
After:
int i = aaaaaa ? 1 //
: [] {
return 2; //
}();
llvm::errs() << "number of twos is "
<< std::count_if(v.begin(), v.end(), [](int x) {
return x == 2; // force break
});

Some compilers warn about using the ternary operator with an unsigned variable
and enum.
I haven't seen this trigger in the llvm.org buildbots yet, but it probably will
at some point.

Summary:
This adds three Function methods to handle function entry counts:
setEntryCount() and getEntryCount().
Entry counts are stored under the MD_prof metadata node with the name
"function_entry_count". They are unsigned 64 bit values set by profilers
(instrumentation and sample profiler changes coming up).
Added documentation for new profile metadata and tests.

Summary:
This patch is the beginnings of support for Non-stop mode in the remote protocol. Letting a user examine stopped threads, while other threads execute freely.
Non-stop mode is enabled using the setting target.non-stop-mode, which sends a QNonStop packet when establishing the remote connection.
Changes are also made to treat the '?' stop reply packet differently in non-stop mode, according to spec https://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Non_002dStop.html#Remote-Non_002dStop.
A setting for querying the remote for default thread on setup is also included.
Handling of '%' async notification packets will be added next.

Several updates for [DebugInfo] Add debug locations to constant SD nodes (r235989).
Includes:
* re-enabling the change (disabled recently);
* missing change for FP constants;
* resetting debug location of constant node if it's used more than at one place
to prevent emission of wrong locations in case of coalesced constants;
* a couple of additional tests.
Now all look ups in CSEMap are wrapped by additional method.
Comment in D9084 suggests that debug locations aren't useful for "target constants",
so there might be one more change related to this API (namely, dropping debug
locations for getTarget*Constant methods).

Previously, subtarget features were a bitfield with the underlying type being uint64_t.
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.
The first two times this was committed (r229831, r233055), it caused several buildbot failures.
At least some of the ARM and MIPS ones were due to gcc/binutils issues, and should now be fixed.
