Tim Northover 6833e3fd75 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.

Jordan Rose c7b992edcf [analyzer] SATestBuild: Don't require reference results to have logs.
The Logs directory isn't used for testing, so it's filtered out ahead of
time. However, there's then no reason to include it in version control at
all. Don't error if it's not present.

Richard Trieu bb4b894e0b Add a new warning, -Wlogical-not-parentheses, to -Wparentheses.
This warning triggers on the logical not of a non-boolean expression on the
left hand side of comparison.  Often, the user meant to negate the comparison,
not just the left hand side of the comparison.  Two notes are also emitted,
the first with a fix-it to add parentheses around the comparison, and the other
to put parenthesis around the not expression to silence the warning.

bool not_equal(int x, int y) {
  return !x == y;  // warn here
}

  return !(x == y);  // first fix-it, to negate comparison.

  return (!x) == y;  // second fix-it, to silence warning.

Ulrich Weigand 4c44032aa1 [PowerPC] Support extended sc mnemonic
A plain "sc" without argument is supposed to be treated like "sc 0"
by the assembler.  This patch adds a corresponding alias.

Ulrich Weigand aa4a2d71aa [PowerPC] Support branch mnemonics with implied CR0
The extended branch mnemonics are supposed to use an implied CR0
if there is no explicit condition register specified.  This patch
adds extra variants of the mnemonics to this effect.

Reed Kotler ce510830c5 Fix a regression I introduced when I expanded the complex pseudos in
the Mips16 port. A few of the psuedos could either take signed
or unsigned arguments and I did not distinguish the case and improperly
rejected some valid cases that the assembler had previously accepted
when they were pure pseudos that expanded as assembly instructions.

Reid Kleckner 200fe22a13 [CodeGen] Move EHScopeStack to CGCleanup.h from CodeGenFunction.h
No functionality change.  CGCleanup.cpp provides the implementation for
EHScopeStack, so it seems more consistent to place the class definition
in CGCleanup.h.

This should also help solve a header ordering problem that I have.

Logan Chien 1bd6e13b70 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)
