With this commit, all DIEs created in CompileUnit will be added to parents
inside the same function. Also make getOrCreateTemplateType|Value functions
private.
No functionality change.

This is another (final?) stab at making us able to parse our own asm output
on Windows.
Symbols on Windows often contain @'s and ?'s in their names. Our asm parser
didn't like this. ?'s were not allowed, and @'s were intepreted as trying to
reference PLT/GOT/etc.
We can't just add quotes around the bad names, since e.g. for MinGW, we use gas
to assemble, and it doesn't like quotes in some places (notably in .def
directives).
This commit makes us allow ?'s in symbol names, and @'s in symbol names for MS
assembly.

Removing Host/Atomic.h
This header file was not being copied as part of our public API headers and this in turn was causing any plugin to link against LLDB.framework, since SharingPtr.h depends on it
Out of several possible options to fix this issue, the cleanest one is to revert LLDB to use std::atomic<>, as we are a C++11 project and should take advantage of it
The original rationale for going from std::atomic to Host/Atomic.h was that MSVC++ fails to link in CLR mode when std::atomic is used
This is a very Visual Studio/.net specific issue, which hopefully will be fixed
Until them, to allow Windows development to proceed, we are going with a targeted solution where we #ifdef include the Windows specific calls, and let everyone else use the
proper atomic support, as should be
If there is an unavoidable need for a LLDB-specific atomic header, the right way to go at it would be to make an API/lldb-atomic.h header and #ifdef the Windows dependency there
The FormatManager should not need to conditionalize use of std::atomic<>, as other parts of the LLDB internals are successfully using atomic (Address and IRExecutionUnit), so this
Win-specific hack is limited to SharingPtr

Before, clang-format would not adjust leading indents if it found a
structural error (e.g. unmatched {}). It seems, however, that
clang-format has gotten good enough at parsing the code structure that
this hurts in almost all cases. Commonly, while writing code, it is
very useful to be able to correclty indent incomplete if statements or
for loops.
In case this leads to errors that we don't anticipate, we need to find
out and fix those.
This fixed llvm.org/PR17594.

This looks ugly and leads to llvm.org/PR17590.
Before (with AlwaysBreakBeforeMultilineStrings):
return
"aaaa"
"bbbb";
After:
return "aaaa"
"bbbb";

Specifically, prefer breaking before trailing annotations over breaking
before the first parameter.
Before:
void ffffffffffffffffffffffff(
int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) OVERRIDE;
After:
void ffffffffffffffffffffffff(int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
OVERRIDE;

PR17168 describes a test case that fails when compiling for debug with
fast-isel. Investigation showed that the test was failing because a DBG_VALUE
machine instruction was placed prior to a PHI.
For this problem to occur requires the following:
* Compile for debug
* Compile with fast-isel
* In a block B, fast-isel must partially succeed before punting to DAG-isel
* B must start with a PHI
* The first unhandled node in the DAG must not generate a machine instruction
* A debug value with an order less than that of that first node exists
When all of these circumstances apply, the existing test that an instruction
was not inserted won't fire. Currently it tests whether the block is empty,
or whether the last instruction generated is a phi. When fast-isel has
partially succeeded, the last instruction generated will not be a phi.
Instead, we need to check whether the current insert position is immediately
following a phi. This patch adds that check, and adds the test case from the
PR as a regression test.

This commit adds an example python file that can be used with 'target-definition-file' setting for Linux gdbserver.
This file has an extra key 'breakpoint-pc-offset' that LLDB uses to determine how much to change the PC
after hitting the breakpoint.

There are targets that support i128 sized scalars but cannot emit
instructions that modify them directly. The proper thing to do is to
emit a libcall.
This fixes PR17481.

gcc diagnoses this:
warning: converting to non-pointer type 'unsigned int' from NULL
Also remove an empty statement.
No change in functionality.
