[Hexagon] Use constant extenders to fix up hardware loops Use a loop instruction with a constant extender for a hardware loop instruction that is too far away from the start of the loop. This is cheaper than changing the SA register value.

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215558 91177308-0d34-0410-b5e6-96231b3b80d8

[Hexagon] Update AnalyzeBranch, etc target hooks Improved the AnalyzeBranch, InsertBranch, and RemoveBranch functions in order to handle more of our branch instructions.

Revert r155365, r155366, and r155367. All three of these have regression test suite failures. The failures occur at each stage, and only get worse, so I'm reverting all of them. Please resubmit these patches, one at a time, after verifying that the regression test suite passes. Never submit a patch without running the regression test suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155372 91177308-0d34-0410-b5e6-96231b3b80d8

[Hexagon] Update AnalyzeBranch, etc target hooks Improved the AnalyzeBranch, InsertBranch, and RemoveBranch functions in order to handle more of our branch instructions. This requires changes to analyzeCompare and PredicateInstructions.
