5769e19790 [RewriteStatepointsForGC] Delete trivial code
A bit more code cleanup: delete some a trivial true assertion and supporting code, remove a redundant cast, and use count in assertions where feasible.

476706ed94 IR: Extract a function 'printLLVMNameWithoutPrefix' from 'PrintLLVMName'. NFC.
This commit extracts the code that prints out a name of an LLVM value without a
prefix from a function 'PrintLLVMName' into a publicly accessible function named
'printLLVMNameWithoutPrefix'.

This change would be useful for MIR serialization, as it would allow the MIR
printer to reuse this function to print out the names of the external symbol
machine operands.

791500fa0d [CMake] Projects supported via LLVM_EXTERNAL_*_SOURCE_DIR need to be explicitly specified.
One part of my refactoring from r242705 is untenable due to how CMake caches variables. There is no way other than caching to allow variables to be set in one directory and globally readable, but we really don't want to cache the temporary value marking that a directory has already been included.

27ac0fae47 [ARM] Define subtarget feature "reserve-r9", which is used to decide
whether register r9 should be reserved.

This recommits r242737, which broke bots because the number of subtarget
features went over the limit of 64.

This change is needed because we cannot use a backend option to set
cl::opt "arm-reserve-r9" when doing LTO.

Out-of-tree projects currently using cl::opt option "-arm-reserve-r9" to
reserve r9 should make changes to add subtarget feature "reserve-r9" to
the IR.

Re-apply of r241928 which had to be reverted because of the r241926
revert.

This commit factors out common code from MergeBaseUpdateLoadStore() and
MergeBaseUpdateLSMultiple() and introduces a new function
MergeBaseUpdateLSDouble() which merges adds/subs preceding/following a
strd/ldrd instruction into an strd/ldrd instruction with writeback where
possible.

9994b911f4 Targets: commonize some stack realignment code
This patch does the following:
* Fix FIXME on `needsStackRealignment`: it is now shared between multiple targets, implemented in `TargetRegisterInfo`, and isn't `virtual` anymore. This will break out-of-tree targets, silently if they used `virtual` and with a build error if they used `override`.
* Factor out `canRealignStack` as a `virtual` function on `TargetRegisterInfo`, by default only looks for the `no-realign-stack` function attribute.

Multiple targets duplicated the same `needsStackRealignment` code:
 - Aarch64.
 - ARM.
 - Mips almost: had extra `DEBUG` diagnostic, which the default implementation now has.
 - PowerPC.
 - WebAssembly.
 - x86 almost: has an extra `-force-align-stack` option, which the default implementation now has.

The default implementation of `needsStackRealignment` used to just return `false`. My current patch changes the behavior by simply using the above shared behavior. This affects:
 - AMDGPU
 - BPF
 - CppBackend
 - MSP430
 - NVPTX
 - Sparc
 - SystemZ
 - XCore
 - Out-of-tree targets
This is a breaking change! `make check` passes.

The only implementation of the `virtual` function (besides the slight different in x86) was Hexagon (which did `MF.getFrameInfo()->getMaxAlignment() > 8`), and potentially some out-of-tree targets. Hexagon now uses the default implementation.

`needsStackRealignment` was being overwritten in `<Target>GenRegisterInfo.inc`, to return `false` as the default also did. That was odd and is now gone.

Summary:
Arguments to llvm.localescape must be static allocas. They must be at
some statically known offset from the frame or stack pointer so that
other functions can access them with localrecover.

If we ever want to instrument these, we can use more indirection to
recover the addresses of these local variables. We can do it during
clang irgen or with the asan module pass.

679d26ce56 MachineScheduler: Restrict macroop fusion to data-dependent instructions.
Before creating a schedule edge to encourage MacroOpFusion check that:
- The predecessor actually writes a register that the branch reads.
- The predecessor has no successors in the ScheduleDAG so we can
  schedule it in front of the branch.

This avoids skewing the scheduling heuristic in cases where macroop
fusion cannot happen.

b2dab382ce [ARM] Refactor the prologue/epilogue emission to be more robust.
This is the first step toward supporting shrink-wrapping for this target.

The changes could be summarized by these items:
- Expand the tail-call return as part of the expand pseudo pass.
- Get rid of the assumptions that the epilogue is the exit block:
  * Do not assume which registers are free in the epilogue. (This indirectly
    improve the lowering of the code for the segmented stacks, see the test
    cases.)
  * Take into account that the basic block can be empty.

0e4484f44d MIR Serialization: Initial serialization of machine constant pools.
This commit implements the initial serialization of machine constant pools and
the constant pool index machine operands. The constant pool is serialized using
a YAML sequence of YAML mappings that represent the constant values.
The target-specific constant pool items aren't serialized by this commit.
