The new ORC remote-JITing support provides a superset of the old code's
functionality, so we can replace the old stuff. As a bonus, a couple of
previously XFAILed tests have started passing.

As soon as a comment had whitespace changes inside of the token, we
couldn't identify the whole comment as a trailing comment anymore and
alignment stopped working. Add a new boolean to Change for this special
case and fix trailing comment identification to use it.
This also changes WhitespaceManager to sum the length of all Changes
inside of a token into the first Change.
Before this fix
int xy; // a
int z; //b
became
int xy; // a
int z; // b
with this patch we immediately get to:
int xy; // a
int z; // b

Previously we tried to parse the line table even if a compile unit
had no DW_AT_stmt_list atribute. The problem happens when a compiler
generates debug info for a compile unit but doesn't generate any line
info.

R_AARCH64_TSTBR14 is calculated as S+A-P,
Set the immediate field of a TBZ/TBNZ instruction to bits [15:2] of X; check -2^15 ≤ X < 2^15

R_AARCH64_CONDBR19 is calculated as S+A-P,
Set the immediate field of a conditional branch instruction to bits [20:2] of X; check -2^20 ≤ X< 2^20.
Afaik there is no document for AARCH64 instruction encoding from official for unknown reason, so
I used gold source code and next link as a reference for implementation: http://kitoslab-eng.blogspot.ru/2012/10/armv8-aarch64-instruction-encoding.html. From which is clear that immediate field of a conditional branch instruction is 5 bits off. That is proved by output which is is equal to gold/bfd now.

* Added instructions to generate R_X86_64_32 relocations. Without that next part of code was uncovered by test, code worked without it:
bool X86_64TargetInfo::relocNeedsPlt(uint32_t Type, const SymbolBody &S) const {
if (needsCopyRel(Type, S))
return false;
* Removed -e main, added _start

In the OptimizeLEA pass keep instructions' positions in the basic block saved and use them for calculation of the distance between two instructions instead of std::distance. This reduces complexity of the pass from O(n^3) to O(n^2) and thus the compile time.

r257257 change the way clang-format enforces line breaks after a
templated type has been line-wrapped. This was to fix an incorrect line
break if BinPackParameters is set to false. However, it also leads to
an unwanted line break in a different case. Thus, for now, only do this
when BinPackParameters is false. This isn't ideal yet, but helps us
until we have a better solution.
With BinPackParameters:
Before:
void fffffffffff(aaaaaaaaaaaaaaaaaaaaaaaaaaa<aaaaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaa> aaaaaaaaaa);
After:
void fffffffffff(
aaaaaaaaaaaaaaaaaaaaaaaaaaa<aaaaaaaaaaaaaaaaaaaaaaa, aaaaaaaaaa>
aaaaaaaaaa);

The test hangs/crashes/fails because it does not use the listener API in a way that LLDB expects.
I don't really know if this is the fault of LLDB of the test...

google-runtime-memset no longer issues a warning if the fill char value
is known to be an invalid fill char count.
Namely, it no longer warns for these:
memset(p, 0, 0);
memset(p, -1, 0);
In both cases, swapping the last two args would either be useless (there is
no actual bug) or wrong (it would introduce a bug).

Summary:
On linux we need the process to give us special permissions before we can attach to it.
Previously, the code for this was copied into every file that needed it. This moves the code to a
central place to reduce code duplication.

visited decls.
Due to redeclarations, the function may have different declarations used
in CallExpr and in the definition. However, we need to use a unique
declaration for both store and lookup in VisitedCallees. This patch
fixes issues with analysis in topological order. A simple test is
included.

This patch adds utilities to ORC for managing a remote JIT target. It consists
of:
1. A very primitive RPC system for making calls over a byte-stream. See
RPCChannel.h, RPCUtils.h.
2. An RPC API defined in the above system for managing memory, looking up
symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h.
3. An interface for creating high-level JIT components (memory managers,
callback managers, stub managers, etc.) that operate over the RPC API. See
OrcRemoteTargetClient.h.
4. A helper class for building servers that can handle the RPC calls. See
OrcRemoteTargetServer.h.
The system is designed to work neatly with the existing ORC components and
functionality. In particular, the ORC callback API (and consequently the
CompileOnDemandLayer) is supported, enabling lazy compilation of remote code.
Assuming this doesn't trigger any builder failures, a follow-up patch will be
committed which tests these utilities by using them to replace LLI's existing
remote-JITing demo code.
