SuccessChanges

Summary

  1. ARM: use divmod libcalls on embedded MachO platforms too. The separated libcalls are implemented in terms of __divmodsi4 and __udivmodsi4 anyway, so we should always use them if possible.
  2. Don't add DBG_VALUE instructions for static allocas in dbg.declare Summary: An llvm.dbg.declare of a static alloca is always added to the MachineFunction dbg variable map, so these values are entirely redundant. They survive all the way through codegen to be ignored by DWARF emission. Effectively revert r113967 Two bugpoint-reduced test cases from 2012 broke as a result of this change. Despite my best efforts, I haven't been able to rewrite the test case using dbg.value. I'm not too concerned about the lost coverage because these were reduced from the test-suite, which we still run.

  3. Add some useful helper methods / operators to TypeIndex.
  4. Update instructions for using the experimental monorepo
  5. [BitVector] Make find_prev member function const. NFC.

ARM: use divmod libcalls on embedded MachO platforms too.

The separated libcalls are implemented in terms of __divmodsi4 and __udivmodsi4
anyway, so we should always use them if possible.

Don't add DBG_VALUE instructions for static allocas in dbg.declare

Summary:
An llvm.dbg.declare of a static alloca is always added to the
MachineFunction dbg variable map, so these values are entirely
redundant. They survive all the way through codegen to be ignored by
DWARF emission.

Effectively revert r113967

Two bugpoint-reduced test cases from 2012 broke as a result of this
change. Despite my best efforts, I haven't been able to rewrite the test
case using dbg.value. I'm not too concerned about the lost coverage
because these were reduced from the test-suite, which we still run.
