5e6e8c7a0a CodeGen: Use MachineInstr& in AntiDepBreaker API, NFC 
Take parameters as MachineInstr& instead of MachineInstr* in
AntiDepBreaker API, since these are required to be non-null.  No
functionality change intended.  Looking toward PR26753.

f00654e31b Revert r240137 (Fixed/added namespace ending comments using clang-tidy. NFC) 
Apparently, the style needs to be agreed upon first.

70bc5f1398 Fixed/added namespace ending comments using clang-tidy. NFC 
The patch is generated using this command:

tools/clang/tools/extra/clang-tidy/tool/run-clang-tidy.py -fix \
  -checks=-*,llvm-namespace-comment -header-filter='llvm/.*|clang/.*' \
  llvm/lib/


Thanks to Eugene Kosov for the original patch!

f817c1cb9a Use 'override/final' instead of 'virtual' for overridden methods 
The patch is generated using clang-tidy misc-use-override check.

This command was used:

  tools/clang/tools/extra/clang-tidy/tool/run-clang-tidy.py \
    -checks='-*,misc-use-override' -header-filter='llvm|clang' \
    -j=32 -fix -format

a7c40ef022 Canonicalize header guards into a common format. 
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

079b96e6f7 Revert "Give internal classes hidden visibility." 
It works with clang, but GCC has different rules so we can't make all of those
hidden. This reverts commit r190534.

802d755533 Sort includes for all of the .h files under the 'lib' tree. These were 
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]
