Eugene Zelenko 342257ea92 [ARM] Fix some Clang-tidy modernize and Include What You Use warnings; other minor fixes (NFC).

Benjamin Kramer 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.

Saleem Abdulrasool d9f086036a ARM IAS: add support for .unwind_raw directive
This implements the unwind_raw directive for the ARM IAS.  The unwind_raw
directive takes the form of a stack offset value followed by one or more bytes
representing the opcodes to be emitted.  The opcode emitted will interpreted as
if it were assembled by the opcode assembler via the standard unwinding
directives.

Thanks to Logan Chien for an extra test!

Saleem Abdulrasool b961c99f1a ARM: move ARMUnwindOp.h into Support
Move the ARM EHABI unwind opcode definitions from the ARM MCTargetDesc into LLVM
Support.  This enables sharing of the definitions across the ARM target code as
well as llvm-readobj.  This will allow implementation of the unwind decoding in
llvm-readobj.

Logan Chien 325823a189 Fix ARM unwind opcode assembler in several cases.
Changes to ARM unwind opcode assembler:

* Fix multiple .save or .vsave directives.  Besides, the
  order is preserved now.

* For the directives which will generate multiple opcodes,
  such as ".save {r0-r11}", the order of the unwind opcode
  is fixed now, i.e. the registers with less encoding value
  are popped first.

* Fix the $sp offset calculation.  Now, we can use the
  .setfp, .pad, .save, and .vsave directives at any order.

Changes to test cases:

* Add test cases to check the order of multiple opcodes
  for the .save directive.

* Fix the incorrect $sp offset in the test case.  The
  stack pointer offset specified in the test case was
  incorrect.  (Changed test cases: ehabi-mc-section.ll and
  ehabi-mc.ll)

* The opcode to restore $sp are slightly reordered.  The
  behavior are not changed, and the new output is same
  as the output of GNU as.  (Changed test cases:
  eh-directive-pad.s and eh-directive-setfp.s)
