Saleem Abdulrasool f5b8d8249e test: relax the FS test a slight bit to be more reliable
Some filesystems track atime always.  This relaxes the test to accept either a
filesystem which does not accurately track atime or does track the atime
accurately.  This allows the test to pass on filesystems mounted with
`strictatime` on Linux or on macOS.

Sebastian Pop 51b4aee94f Add 'inline' attribute to __init to inline the basic_string's constructor
basic_string's constructor calls init which was not getting inlined.  This
prevented optimization of const string as init would appear as a call in between
a string's def and use.

Duncan P. N. Exon Smith ec30cc2171 Hexagon: Avoid dereferencing end() in HexagonCopyToCombine::findPairable
Check for end() before skipping through debug values.  This avoids
dereferencing end() when the instruction is the final one in the basic
block.  (It still assumes that a debug value will not be the final
instruction in the basic block.  No tests seemed to violate that.)

Many Hexagon tests trigger this, but they happen to magically pass right
now.  I found this because WIP patches for PR26753 convert them into
crashes.

Lang Hames 30526070ab [MCJIT] Improve documentation and error handling for MCJIT::runFunction.
ExecutionEngine::runFunction is supposed to allow execution of arbitrary
function types, but MCJIT can only reasonably support a limited subset of
main-linke function types. This patch documents this limitation, and fixes
MCJIT::runFunction to abort with a meaningful error at runtime if called with
an unsupported function type.

Stop casting to it just to get an iterator back.

(although this is relying on UB, I doubt it was triggering anything),
but I'll be removing the cast soon.

Teresa Johnson 9ba95f99f3 Restore "Resolution-based LTO API."
This restores commit r278330, with fixes for a few bot failures:
- Fix a late change I had made to the save temps output file that I
  missed due to existing files sitting on my disk
- Fix a bunch of Windows bot failures with "ambiguous call to overloaded
  function" due to confusion between llvm::make_unique vs
  std::make_unique (preface the new make_unique calls with "llvm::")
- Attempt to fix a modules bot failure by adding a missing include
  to LTO/Config.h.

Original change:

Resolution-based LTO API.

Summary:
This introduces a resolution-based LTO API. The main advantage of this API over
existing APIs is that it allows the linker to supply a resolution for each
symbol in each object, rather than the combined object as a whole. This will
become increasingly important for use cases such as ThinLTO which require us
to process symbol resolutions in a more complicated way than just adjusting
linkage.

Ehsan Amiri b9fcc2b171 Extend trip count instead of truncating IV in LFTR, when legal
When legal, extending trip count in the loop control logic generates better code compared to truncating IV. This is because

(1) extending trip count is a loop invariant operation (see genLoopLimit where we prove trip count is loop invariant).
(2) Scalar Evolution seems to have problems understanding trunc when computing loop trip count. So removing them allows better analysis performed in Scalar Evolution. (In particular this fixes PR 28363 which is the motivation for this change).

I am not going to perform any performance test. Any degradation caused by this should be an indication of a bug elsewhere.

To prove legality, we rely on SCEV to prove zext(trunc(IV)) == IV (or similarly for sext). If this holds, we can prove equivalence of trunc(IV)==ExitCnt (1) and IV == zext(ExitCnt). Simply take zext of boths sides of (1) and apply the proven equivalence.

The previous implementation (not custom) doesn't enforce zeroing off upper bits. The assumption is that i1 PRODUCER (truncate and extractelement) must zero all upper bits, so i1 CONSUMER instructions ( test, zext, save, etc) can be done without additional zeroing.
Make extractelement i1 lowering custom for all vector i1.

Marina Yatsina 88f0c31f13 Avoid false dependencies of undef machine operands
This patch helps avoid false dependencies on undef registers by updating the machine instructions' undef operand to use a register that the instruction is truly dependent on, or use a register with clearance higher than Pref.

Pseudo example:

loop:
xmm0 = ...
xmm1 = vcvtsi2sdl eax, xmm0<undef>
... = inst xmm0
jmp loop

In this example, selecting xmm0 as the undef register creates false dependency between loop iterations.
This false dependency cannot be solved by inserting an xor before vcvtsi2sdl because xmm0 is alive at the point of the vcvtsi2sdl instruction.
Selecting a different register instead of xmm0, especially a register that is not used in the loop, will eliminate this problem.
