lldb-gdbserver statically links all llvm dependencies. This allows
dead stripping code and reduces total binary size.
This change modifies lldb-plaform to static link llvm dependencies
like lldb-gdbserver.

`MDNode::replaceOperandWith()` changes all instances of metadata. Stop
using it when linking module flags, since (due to uniquing) the flag
values could be used by other metadata.
Instead, use new API `NamedMDNode::setOperand()` to update the reference
directly.

This would add another library dependency to Polly. In many cases the
JSCoP interface we have should be enough and an external JSCoP <> OpenSCoP
converter could be written. We can reconsider this if new use cases show up.

transform.
Also diagnose typos in the initializer of an invalid C++ declaration.
Both issues were hit using the same line of test code, depending on
whether the code was treated as C or C++.
Fixes PR22092.

This commit adds a simple iterator over that enum, and a few
functions to create iterator ranges over the most common types.

options other than just -disassemble so that universal files can be used with other
options combined with -arch options.
No functional change to existing options and use. One test case added for the
additional functionality with a universal file an a -arch option.

Use VGPR_32 register class instead. These two register classes were
identical and having separate classes was causing
SIInstrInfo::isLegalOperands() to be overly conservative in some cases.
This change is necessary to prevent future paches from missing a folding
opportunity in fneg-fabs.ll.

This change includes the most basic possible GCStrategy for a GC which is using the statepoint lowering code. At the moment, this GCStrategy doesn't really do much - aside from actually generate correct stackmaps that is - but I went ahead and added a few extra correctness checks as proof of concept. It's mostly here to provide documentation on how to do one, and to provide a point for various optimization legality hooks I'd like to add going forward. (For context, see the TODOs in InstCombine around gc.relocate.)
Most of the validation logic added here as proof of concept will soon move in to the Verifier. That move is dependent on http://reviews.llvm.org/D6811
There was discussion in the review thread about addrspace(1) being reserved for something. I'm going to follow up on a seperate llvmdev thread. If needed, I'll update all the code at once.
Note that I am deliberately not making a GCStrategy required to use gc.statepoints with this change. I want to give folks out of tree - including myself - a chance to migrate. In a week or two, I'll make having a GCStrategy be required for gc.statepoints. To this end, I added the gc tag to one of the test cases but not others.

Shorter and doesn't need -O2 -- but still suboptimal as it's still doing
-emit-obj. dblaikie says he'll improve this when he'll reland his change
with a fix.

r225141 changed the defaults of AllowShortIfStatementsOnASingleLine and
AlignTrailingComments for Google style and added explicit overrides for
Chromium style to undo these changes. For AllowShortIfStatementsOnASingleLine
that's good as the Android style guide (which Chromium uses for Java) explicitly
permits single-line ifs. But it's silent on trailing comments, to it makes
sense for Chromium style to just follow Google style.

Many places reference MVT::LAST_VALUETYPE when iterating over all
valid MVTs, but they usually start with 0.
With FIRST_VALUETYPE, we can avoid explicit constants when we really
should be using MVT::SimpleValueType.

PR22096 has several test cases that assert that look fairly different. I'm
adding one of those as an automated test, but when relanding the other cases
should probably be checked as well.

LLVM emits stack probes on Windows targets to ensure that the stack is
correctly accessed. However, the amount of stack allocated before
emitting such a probe is hardcoded to 4096.
It is desirable to have this be configurable so that a function might
opt-out of stack probes. Our level of granularity is at the function
level instead of, say, the module level to permit proper generation of
code after LTO.
Patch by Andrew H!
N.B. The inliner needs to be updated to properly consider what happens
after inlining a function with a specific stack-probe-size into another
function with a different stack-probe-size.

* Both files have valid package headers and footers (you can verify
with M-x checkdoc).
* Fixed style warnings generated by checkdoc.
* Fixed a byte-compiler warning in llvm-mode.el.
* Ensure that the modes are autoloaded, so users do not need to
(require 'llvm-mode) to use them.

This prevents clang-format from moving/aligning the comment in the
snippet:
void f() {
int i; // some comment

Used to iterate over previously added memory dependencies in
adjustChainDeps() and iterateChainSucc().
SDep::isCtrl() was previously used in these places, that also gave
anti and output edges. The code may be worse if these are followed,
because MisNeedChainEdge() will conservatively return true since a
non-memory instruction has no memory operands, and a false chain dep
will be added. It is also unnecessary since all memory accesses of
interest will be reached by memory dependencies, and there is a budget
limit for the number of edges traversed.
This problem was found on an out-of-tree target with enabled alias
analysis. No test case for an in-tree target has been found.
