Summary:
This commit integrates MainLoop into NativeProcessLinux. By registering a SIGCHLD handler with
the llgs main loop, we can get rid of the special monitor thread in NPL, which saves as a lot of
thread ping-pong when responding to client requests (e.g. qThreadInfo processing time has been
reduced by about 40%). It also makes the code simpler, IMHO.

This is a resubmission of r242305 after it was reverted due to bad interactions with the stdio
thread.
llvm-svn: 242783
Summary:
This commit removes the stdio forwarding thread in lldb-server in favor of a MainLoop callback.
As in some situations we need to forcibly flush the stream ( => Read() is called from multiple
places) and we still have multiple threads, I have had to additionally protect the communication
instance with a mutex.

Put all Polly targets into a single "Polly" category (i.e.
solution folder). Previously there was no recognizable scheme and most
categories contained just one or two targets or targets didn't belong
to any category.

Remove the polly_headers_do_not_build project. Visual Studio is capable
of finding the headers itself, although they are not listed explicitly.
For explicit listing, the headers should be added to the relevant
target.

Query the isl_config.h macros recently added to ISL. One of it looks for
the ffs (find first set), whose functionality is available in Visual
Studio with _BitScanForward. Also add isl_ffs.c to the source files
which contains the implementation of ffs using _BitScanForward.

Summary:
* Remove extraneous members that were just storing temporary
values.
* ResultClass_e parameters don't need to be const as they are
scalars.
* Switch from a map with CMIUtilString values to using a mapping
function. This uses a switch statement which will generate
a warning if a new result class is added.
* Make BuildRecordResult a static function rather than a private
member function so that we can construct the result text
correctly and avoid having extra stuff in the header.
* Don't need (void) parameter lists in C++.

I have observed an increased flakyness in the buildbots. I suspect something was relying on the
fact that Pipe::Write had an implicit timeout of 1s, which this commit has removed. Reverting
while I investigate.

It should now support three mingw distributions running on Windows
and three Linux distributions. The include directories for each are
listed in the comments.
llvm-svn: 242766
Summary:
This commit adds a WriteWithTimeout method to time Pipe class, analogous to the existing
ReadWithTimeout(). It also changes the meaning of passing zero as a timeout value. Previously,
zero was used as an infinite timeout value. Now, the meaning of zero timeout to return the data
avaiable without sleeping (basically, a non-blocking operation). This makes the behaviour of Pipe
consistent with the Communication/Connection classes. For blocking operatios with infinite
timeout, I introduce a special constant for this purpose.

whether register r9 should be reserved.
This recommits r242737, which broke bots because the number of subtarget
features went over the limit of 64.
This change is needed because we cannot use a backend option to set
cl::opt "arm-reserve-r9" when doing LTO.
Out-of-tree projects currently using cl::opt option "-arm-reserve-r9" to
reserve r9 should make changes to add subtarget feature "reserve-r9" to
the IR.

option "-arm-reserve-r9".
This recommits r242736, which had to be reverted because the llvm-side
change that was committed in r242737 caused the number of subtarget
features to go over the limit of 64.
This change is needed since backend options do not make it to the backend
when doing LTO and are not capable of changing the behavior of code-gen
passes on a per-function basis.

We can use builders to simplify part of the code and we only check for the existance of the metadata value; this enables us to delete some redundant code.

Summary:
As llgoi is installed, it must be built or the install
target will fail; there is no implicit dependency.
Adding llgoi to "ALL" makes building llgo as part of an
entire LLVM distribution a bit friendlier: you can then
just do the typical "make && make install".

Summary:
When calling llgo-go from the llvm_add_go_executable
cmake function, specify $GO_EXECUTABLE as the go
command to call. Without this, llgo-go searches $PATH
which may be inconsistent with $GO_EXECUTABLE.

This can include objects that have complex state and need to be torn down intelligently (e.g. our SB* objects)
This will fail if the Python interpreter does not hold a valid thread state. So, acquire one, delete the session dictionary, and then let go of it on destruction

This commit factors out common code from MergeBaseUpdateLoadStore() and
