Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
LineJoiner iterate over the lines so we never operate on a line that might
be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.
Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
only the outer expression was affected:
int x = s({ // clang-format only this line
class X {
public:
// ^ this starts at the non-modified indnent level; previously we would
// not fix this, now we correctly outdent it.
void f();
};
});
2. We would incorrectly align comments across lines that do not have comments
for lines with nested blocks:
int expression; // with comment
int x = s({
int y; // comment
int z; // we would incorrectly align this comment with the comment on
// 'expression'

Remove handling of eStateStopped from NativeProcessLinux::Resume
Summary:
NPL::Resume attempted to handle eStateStopped as a resume action. However:
- GDBRemoteCommunicationServerLLGS (the only user of NPL) never sets this action
- it could set this action in response to a vCont:t packet, but LLDB never produces this packet
- gdb-remote protocol documentation says vCont:t packet is used only in non-stop mode, but LLDB
does not support non-stop mode
- even if LLDB supported non-stop mode, this implementation of eStateStopped does something
different from what the spec says it should (according to spec, it should stop the specified
thread, but this seems to want to stop all threads).
Given the facts above, I believe we should remove this unused and untested code, as it probably
doesn't even work and removing it makes the rest of the code noticably simpler.

Remove Triple Vendor check when creating Linux Platform
Summary: The Linux Platform shouldn't care about the Vendor field in the Triple. Currently it allows a value of "PC", or "unknown" if LLDB was built on Linux. This patch removes that check, so the Vendor field isn't touched. This will allow the Linux Platform to be created when using a Triple of *-*-Linux.

Fix input validation issues in llvm-as/llvm-dis
Summary:
1. llvm-as/llvm-dis tools do not check for input filename length.
2. llvm-dis does not verify the `Streamer` variable against `nullptr` properly, so the `M` variable could be uninitialized (e.g. if the input file does not exist) leading to null dref.

AsmLabel is heavily used in system level and firmware to redirect

output binary, it shouldn't be considered as inline-asm.

[RewriteStatepointsForGC] Fix a bug on creating gc_relocate for pointer to vector of pointers
Summary:
In RewriteStatepointsForGC pass, we create a gc_relocate intrinsic for
each relocated pointer, and the gc_relocate has the same type with the
pointer. During the creation of gc_relocate intrinsic, llvm requires to
mangle its type. However, llvm does not support mangling of all possible
types. RewriteStatepointsForGC will hit an assertion failure when it
tries to create a gc_relocate for pointer to vector of pointers because
mangling for vector of pointers is not supported.
This patch changes the way RewriteStatepointsForGC pass creates
gc_relocate. For each relocated pointer, we erase the type of pointers
and create an unified gc_relocate of type i8 addrspace(1)*. Then a
bitcast is inserted to convert the gc_relocate to the correct type. In
this way, gc_relocate does not need to deal with different types of
pointers and the unsupported type mangling is no longer a problem. This
change would also ease further merge when LLVM erases types of pointers
and introduces an unified pointer type.
Some minor changes are also introduced to gc_relocate related part in
InstCombineCalls, CodeGenPrepare, and Verifier accordingly.
