When a truncate node defines a legal vector type but uses an illegal
vector type, the legalization process was splitting the vector until
<1 x vector> type, but then it was failing to scalarize the node because
it did not know how to handle TRUNCATE.

The test builds an object file to be able to get into linking mode
with a valid obj file on the command-line. Using clang-cl for this,
which targets win32, caused problems on some buildbots, so just
use regular clang.

Previously we would warn about unused arguments such as /MD when linking.
Clang already has logic to ignore compile-only options, e.g. for -D and -U.
This patch extends that to include clang-cl's compile-only options too.
Also, some clang-cl options should always be ignored. Doing this earlier
means they get ignored both for compilation and link-only invocations.

- ProcessMonitor::[Do|Serve]Operation no longer depend on file descriptors!
- removed unused member functions CloseFD and EnableIPC
- add semaphores to signal when an Operation is ready to be processed/complete.
This commit fixes a bug that was identified under stress-testing (i.e. build
LLVM while running tests) that led to LLDB becoming unresponsive because the
read/write operations on file descriptors in ProcessMonitor were not checked.
Other test runner improvement/convenience:
- pickup environment variables LLDB_LINUX_LOG and LLDB_LINUX_LOG_OPTIONS to
enable (Linux) logging when running the test suite. Example usage:
$ LLDB_LINUX_LOG="mylog.txt" LLDB_LINUX_LOG_OPTIONS="process thread" python dotest.py

Summary:
This fixes several issues with the original implementation:
- Win32 entry points cannot be in namespaces
- A Win32 entry point cannot be a function template, diagnose if we it.
- Win32 entry points cannot be overloaded.
- Win32 entry points implicitly return, similar to main.

If there are no legal integers, assume 1 byte.
This makes more sense than using the pointer size as
a guess for the maximum GPR width.
It is conceivable to want to use some 64-bit pointers
on a target where 64-bit integers aren't legal.

for the frame is one past the address range of the calling function.
- Lowers the fix from RegisterContextLLDB for use with disassembly
- Fixes one of three issues in the disassembly test in TestInferiorAssert.py
Also adds documentation that explains the resolution depths and interface.
Note: This change affects the resolution scope for eSymbolContextFunction
without impacting the performance of eSymbolContextSymbol.
Thanks to Matt Kopec for his review.

Fixed an issue with the lldb/test/lang/cpp/virtual test case had a virtual class that had a DW_TAG_inheritance child that was virtual and had a DW_AT_data_member_location of:
DW_AT_data_member_location( DW_OP_dup, DW_OP_deref, DW_OP_constu(0x00000018), DW_OP_minus, DW_OP_deref, DW_OP_plus )
We failed to evaluate this and then we were passing the incorrect offset back to clang and clang would crash. The AST external source has a function named LayoutRecordType which allows us to supply the virtual base class offsets, but that really doesn't make sense to do as clang will lay them out correctly. So we must ignore virtual base classes when doing layout.

I got a report of a hang in git's helper functions trying to figure out
how to display results of "git svn info" when run inside ninja, even though
the result is immediately piped to grep. This seems to avoid that.

This patch changes lld to go through all sections while calculating the size
for SizeOfCode, SizeOfInitializedData and SizeOfUninitializedData fields in the
PE header, instead of using only a small set of hard-coded sections.
This only really changes SizeOfInitializedData which didn't include .reloc
section before this patch.

Fast-isel generates a COPY_TO_REGCLASS for widening f32 to f64, which
is a nop on PPC64. This is needed to keep the register class system
happy, but on the fast-isel path it is not removed before emit as it
is for DAG select. Ignore this op when emitting instructions.

TableGen was sorting the entries in some of its internal data
structures by pointer. This order filtered through to the final
matching table and affected the diagnostics produced on bad assembly
occasionally.
It also turns out STL algorithms are ridiculously easy to misuse on
containers with custom order methods. (No bugs before, or now that I
know of, but plenty in the middle).
This should fix the sanitizer bot, which ends up with weird pointers.

We would have to compute the pre increment value, either by computing it on
every loop iteration or by splitting the edge out of the loop and inserting a
computation for it there.
For now, just give up vectorizing such loops.
