Sam McCall 3bf9b6d920 [clangd] dexp tool uses llvm::cl to parse its flags.
Summary:
We can use cl::ResetCommandLineParser() to support different types of
command-lines, as long as we're careful about option lifetimes.
(I tried using subcommands, but the error messages were bad)
I found a mostly-reasonable pattern to isolate the fiddly parts.

Added -scope and -limit flags to the `find` command to demonstrate.
(Note that scope support seems to be broken in dex?)

Fixed symbol lookup to parse symbol IDs.

Caveats:
 - with command help (e.g. `find -help`), you also get some spam
   about required arguments. This is a bug in llvm::cl, which prints
   these to errs() rather than the designated stream.

David Green 85d6a55995 [AArch64] Attempt to parse more operands as expressions
This tries to make use of evaluateAsRelocatable in AArch64AsmParser::classifySymbolRef
to parse more complex expressions as relocatable operands. It is hopefully better than
the existing code which only handles Symbol +- Constant.

This allows us to parse more complex adr/adrp, mov, ldr/str and add operands. It also
loosens the requirements on parsing addends in ld/st and mov's and adds a number of
tests.

Sam McCall 3d8051abb8 [CodeComplete] Add completions for filenames in #include directives.
Summary:
The dir component ("somedir" in #include <somedir/fo...>) is considered fixed.
We append "foo" to each directory on the include path, and then list its files.

Completions are of the forms:
 #include <somedir/fo^
                   foo.h>
                   fox/

The filter is set to the filename part ("fo"), so fuzzy matching can be
applied to the filename only.

No fancy scoring/priorities are set, and no information is added to
CodeCompleteResult to make smart scoring possible. Could be in future.

QingShan Zhang f1b0b47b2d [PowerPC] Add Itineraries of IIC_IntMulHD for P7/P8
When doing some instruction scheduling work, we noticed some missing itineraries.
Before we switch to machine scheduler, those missing itineraries might not have impact to actually scheduling, 
because we can still get same latency due to default values.

With machine scheduler, however, itineraries will have impact to scheduling.
eg: NumMicroOps will default to be 0 if there is NO itineraries for specific instruction class.
And most of the instruction class with itineraries will have NumMicroOps default to 1.

This will has impact on the count of RetiredMOps, affects the Pending/Available Queue, 
then causing different scheduling or suboptimal scheduling further.

Ryan Prichard 1c33d14bcd [ELF] Set Out::TlsPhdr earlier for encoding packed reloc tables
Summary:
For --pack-dyn-relocs=android, finalizeSections calls
LinkerScript::assignAddresses and
AndroidPackedRelocationSection::updateAllocSize in a loop,
where assignAddresses lays out the ELF image, then updateAllocSize
determines the size of the Android packed relocation table by encoding it.
Encoding the table requires knowing the values of relocation addends.

To get the addend of a TLS relocation, updateAllocSize can call getSymVA
on a TLS symbol before setPhdrs has initialized Out::TlsPhdr, producing an
error:

    <file> has an STT_TLS symbol but doesn't have an SHF_TLS section

Fix the problem by initializing Out::TlsPhdr immediately after the program
headers are created. The segment's p_vaddr field isn't initialized until
setPhdrs, so use FirstSec->Addr, which is what setPhdrs would use.
FirstSec will typically refer to the .tdata or .tbss output section, whose
(tentative) address was computed by assignAddresses.

Android currently avoids this problem because it uses emutls and doesn't
support ELF TLS. This problem doesn't apply to --pack-dyn-relocs=relr
because SHR_RELR only handles relative relocations without explicit addends
or info.

Shuai Wang 13f5dd5280 [clang-tidy] Fix tests for performance-for-range-copy
Test failed as D52120 made ExprMutationAnalyzer smarter, fixed by:
- Add move-ctor for `Mutable` to make it actually movable.
- Properly implement `remove_reference`.

The failed test case is:
void negativeVarIsMoved() {
  for (auto M : View<Iterator<Mutable>>()) {
    auto Moved = std::move(M);
  }
}
Before D52120, `std::move(M)` itself is considered as a mutation to `M`,
while after D52120 it's only considered as a cast to rvalue, the
move-assignment is what causes the actual mutation. The test case didn't
mock things properly so the intended move-assignement was actually a
