Craig Topper ff66919020 [X86][CostModel] Bump the cost of vpermw/vpermt2b/vperm2w
vpermw is 2 uops. vpermt2b/vpermt2w are two shuffle uops and a port 015 uop. Weirdly vpermb is a single uop.

This patch bumps the cost to 2 for these operations. Maybe should go to 3 for the vpermt2*, but I've started conservative.

I've also removed a few entries that were now the same as earlier subtargets or that I didn't think we really did. Like I don't think we extend v32i8 to v32i16, shuffle, and then truncate.

Aaron Smith 4eabd00612 [Windows SEH] Fix abnormal-exits in _try
Summary:
Per Windows SEH Spec, except _leave, all other early exits of a _try (goto/return/continue/break) are considered abnormal exits.  In those cases, the first parameter passes to its _finally funclet should be TRUE to indicate an abnormal-termination.

One way to implement abnormal exits in _try is to invoke Windows runtime _local_unwind() (MSVC approach) that will invoke _dtor funclet where abnormal-termination flag is always TRUE when calling _finally.  Obviously this approach is less optimal and is complicated to implement in Clang.

Clang today has a NormalCleanupDestSlot mechanism to dispatch multiple exits at the end of _try.  Since  _leave (or try-end fall-through) is always Indexed with 0 in that NormalCleanupDestSlot,  this fix takes the advantage of that mechanism and just passes NormalCleanupDest ID as 1st Arg to _finally.

Fangrui Song b257d3c8a8 [ELF][PPC64] Suppress toc-indirect to toc-relative relaxation if R_PPC64_TOC16_LO is seen
The current implementation assumes that R_PPC64_TOC16_HA is always followed
by R_PPC64_TOC16_LO_DS. This can break with R_PPC64_TOC16_LO:

  // Load the address of the TOC entry, instead of the value stored at that address
  addis 3, 2, .LC0@tloc@ha  # R_PPC64_TOC16_HA
  addi  3, 3, .LC0@tloc@l   # R_PPC64_TOC16_LO
  blr

which is used by boringssl's util/fipstools/delocate/delocate.go
https://github.com/google/boringssl/blob/master/crypto/fipsmodule/FIPS.md has some documentation.
In short, this tool converts an assembly file to avoid any potential relocations.
The distance to an input .toc is not a constant after linking, so it cannot use an `addis;ld` pair.
Instead, it jumps to a stub which loads the TOC entry address with `addis;addi`.

This patch checks the presence of R_PPC64_TOC16_LO and suppresses
toc-indirect to toc-relative relaxation if R_PPC64_TOC16_LO is seen.
This approach is conservative and loses some relaxation opportunities but is easy to implement.

  addis 3, 2, .LC0@toc@ha  # no relaxation
  addi  3, 3, .LC0@toc@l   # no relaxation
  li    9, 0
  addis 4, 2, .LC0@toc@ha  # can relax but suppressed
  ld    4, .LC0@toc@l(4)   # can relax but suppressed

Also note that interleaved R_PPC64_TOC16_HA and R_PPC64_TOC16_LO_DS is
possible and this patch accounts for that.

  addis 3, 2, .LC1@toc@ha  # can relax
  addis 4, 2, .LC2@toc@ha  # can relax
  ld    3, .LC1@toc@l(3)   # can relax
  ld    4, .LC2@toc@l(4)   # can relax

Louis Dionne 2fd7d364cd [libc++] Make the verify-support feature implicit
Tests that require support for Clang-verify are already marked as such
explicitly by their extension, which is .verify.cpp. Requiring the use
of an explicit Lit feature is, after thought, not really helpful.

This is a change in design: we have been bitten in the past by tests not
being enabled when we thought they were. However, the issue was mostly
with file extensions being ignored. The fix for that is not to blindly
require explicit features all the time, but instead to report all files
that are in the suite but that don't match any known test format. This
can be implemented in a follow-up patch.

Jann Horn cfe36e4c6a [AddressSanitizer] Refactor: Permit >1 interesting operands per instruction
Summary:
Refactor getInterestingMemoryOperands() so that information about the
pointer operand is returned through an array of structures instead of
passing each piece of information separately by-value.

This is in preparation for returning information about multiple pointer
operands from a single instruction.

A side effect is that, instead of repeatedly generating the same
information through isInterestingMemoryAccess(), it is now simply collected
once and then passed around; that's probably more efficient.

HWAddressSanitizer has a bunch of copypasted code from AddressSanitizer,
so these changes have to be duplicated.
