One call `makeRule` is unqualified (and unintentionally relying on ADL to
resolve correctly). This revision qualifies that call for consistency and to
drop use of ADL.

Summary:
This patch changes the location specified to the
`ClangTidyCheck::diag()`. Currently, the beginning of the matched range is
used. This patch uses the beginning of the first fix's range. This change both
simplifies the code and (hopefully) gives a more intuitive result: the reported
location aligns with the fix(es) provided, rather than the (arbitrary) range of
the rule's match.
N.B. this patch will break the line offset numbers in lit tests if the first fix
is not at the beginning of the match.

Just reapplies highlightings for all files when visible text editors change. Could find the correct text editor that should be reapplied but going for a simple implementation instead.

My previous attempt in attempt in r369904 actually broke the 32bit build
because File::Read expects to take a reference to size_t. Fix the
warning by using SIZE_MAX to denote failure instead.

Constructing a std::vector from a llvm::map_range fails on windows,
apparently because std::vector expects the input iterator to have a
const operator* (map_range iterator has a non-const one).
This avoids the cleverness and unrolls the map-loop manually (which is
also slightly shorter).
llvm-svn: 369905
Summary:
Previously we moved the code which parses a single expression out of the PDB
plugin, because that was useful for DWARF expressions in breakpad. However, FPO
programs are used in breakpad files too (when unwinding on windows), so this
completes the job, and moves the rest of the FPO parser too.

llvm-svn: 369894
Summary:
Adds the main colorizer component. It colorizes every time clangd sends a publishSemanticHighlighting notification.
Every time it colorizes it does a full recolorization (removes all decorations from the editor and applies new ones). The reason for this is that all ranges for the same scope share a TextEditorDecorationType. This is due to TextEditorDecorationTypes being very expensive to create. The prototype used one DecorationType per range but that ran into very big performance problems (it took >100 ms to apply 600 lines of highlightings which froze the editor).
This version does not share the problem of being extremly slow, but there is probably potential to optimize it even more.
No document/texteditor lifecycle management code in this CL, that will come in the next one.

This is a fixup for r369823 which introduced the use of

Minimum supported version of cmake in LLVM is 3.4.3 and
VERSION_GREATER_EQUAL was not introduced until later
versions of cmake.

EhFrameSection::addSection checks liveness of FDE early. This makes it
infeasible to move combineEhSections() before ICF.
Postpone the check to EhFrameSection::finalizeContents(). This is what
ARMExidxSyntheticSection does and it will make a subsequent patch D66717
simpler.

PR42990. For `SECTIONS { b = a; . = 0xff00 + (a >> 8); a = .; }`,
we currently set st_value(a)=0xff00 while st_value(b)=0xffff.
The following call tree demonstrates the problem:
```
link<ELF64LE>(Args);
Script->declareSymbols(); // insert a and b as absolute Defined
Writer<ELFT>().run();
Script->processSectionCommands();
addSymbol(cmd); // a and b are re-inserted. LinkerScript::getSymbolValue
// is lazily called by subsequent evaluation
finalizeSections();
forEachRelSec(scanRelocations<ELFT>);
processRelocAux // another problem PR42506, not affected by this patch
finalizeAddressDependentContent(); // loop executed once
script->assignAddresses(); // a = 0, b = 0xff00
script->assignAddresses(); // a = 0xff00, _end = 0xffff
```
We need another assignAddresses() to finalize the value of `a`.
This patch
1) modifies assignAddress() to track the original section/value of each
symbol and return a symbol whose section/value has changed.
2) moves the post-finalizeSections assignAddress() inside the loop
of finalizeAddressDependentContent() and makes it iterative.
Symbol assignment may not converge so we make a few attempts before
bailing out.
Note, assignAddresses() must be called at least twice. The penultimate
call finalized section addresses while the last finalized symbol values.
It is somewhat obscure and there was no comment.
linkerscript/addr-zero.test tests this.

Summary:
When reconstructing the CFG of the loop after unrolling,
LoopUnroll could in some cases remove the phi operands of
loop-carried values instead of preserving them, resulting
in undef phi values after loop unrolling.
When doing this reconstruction, avoid removing incoming
phi values for phis in the successor blocks if the successor
is the block we are jumping to anyway.

Summary:
We should always have a dummy target, so we might as well construct it directly when we create a Debugger object.
The idea is that if this patch doesn't cause any problems that we can get rid of all the logic
that handles situations where we don't have a dummy target (as all that code is currently
untested as there seems to be no way to have no dummy target in LLDB).

Let's just disallow the combination. In some cases the combination can

Patch by Mark de Wever.
llvm-svn: 369873
Summary:
Concat_vectors is more canonical during early DAG combine. For example, its what's used by SelectionDAGBuilder when converting IR shuffles into SelectionDAG shuffles when element counts between inputs and mask don't match. We also have combines in DAGCombiner than can pull concat_vectors through a shuffle. See partitionShuffleOfConcats. So it seems like concat_vectors is a better operation to use here. I had to teach DAGCombiner's SimplifyVBinOp to also handle concat_vectors with undef. I haven't checked yet if we can remove the INSERT_SUBVECTOR version in there or not.
I didn't want to mess with the other caller of getShuffleHalfVectors that's used during shuffle lowering where insert_subvector probably is what we want to produce so I've enabled this via a boolean passed to the function.
