3862709058 ARM: Fix STREX/LDREX reecoding
The decoded MCInst wasn't reencoded as the same instruction

c139672407 Tweak a couple of tests on win32 hosts with +Asserts.
- Don't use assert(0), or tests may pass or fail according to assertions.
  - For now, The tests are marked as XFAIL for win32 hosts.

FIXME: Could we avoid XFAIL to specify triple in the RUN lines?

9bdd785014 ARM: diagnose ARM/Thumb assembly switches on CPUs only supporting one.
Some ARM CPUs only support ARM mode (ancient v4 ones, for example) and some
only support Thumb mode (M-class ones currently). This makes sure such CPUs
default to the correct mode and makes the AsmParser diagnose an attempt to
switch modes incorrectly.

e5609f3732 X86: Stop LEA64_32r doing unspeakable things to its arguments.
Previously LEA64_32r went through virtually the entire backend thinking it was
using 32-bit registers until its blissful illusions were cruelly snatched away
by MCInstLower and 64-bit equivalents were substituted at the last minute.

This patch makes it behave normally, and take 64-bit registers as sources all
the way through. Previous uses (for 32-bit arithmetic) are accommodated via
SUBREG_TO_REG instructions which make the types and classes agree properly.

b0ee97a366 Fix a regression I introduced when I expanded the complex pseudos in

when they were pure pseudos that expanded as assembly instructions.

c8ecf53082 Refine the ARM EHABI test cases.
Since we have ARM unwind directive parser and assembler, we
can check the correctness in two stages:

1. From LLVM assembly (.ll) to ARM assembly (.s)
2. From ARM assembly (.s) to ELF object file (.o)

We already have several "*.s to *.o" test cases.  This CL adds
some "*.ll to *.s" test cases and removes the redundant "*.ll to *.o"
test cases.

New test cases to check "*.ll to *.s" code generator:

- ehabi.ll: Check the correctness of the generated unwind directives.
- section-name.ll: Check the section name of functions.

Removed test cases:

- ehabi-mc-cantunwind.ll
  (Covered by ehabi-cantunwind.ll, and eh-directive-cantunwind.s)
- ehabi-mc-compact-pr0.ll
  (Covered by ehabi.ll, eh-compact-pr0.s, eh-directive-save.s, and
   eh-directive-setfp.s)
- ehabi-mc-compact-pr1.ll
  (Covered by ehabi.ll, eh-compact-pr1.s, eh-directive-save.s, and
   eh-directive-setfp.s)
- ehabi-mc.ll
  (Covered by ehabi.ll, and eh-directive-integrated-test.s)
- ehabi-mc-section-group.ll
  (Covered by section-name.ll, and eh-directive-section-comdat.s)
- ehabi-mc-section.ll
  (Covered by section-name.ll, and eh-directive-section.s)
- ehabi-mc-sh_link.ll
  (Covered by eh-directive-text-section.s, and eh-directive-section.s)

18cba562c8 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)

as the call in question may never return, and in this case, the derived
