Check the actual memory type stored and not the extended value size
when considering if truncated store merge is worthwhile.

It cuts clangFormat's dependencies out of;

  Clang_Analysis
  Clang_C
  Clang_Diagnostics
  Clang_Driver
  Clang_Frontend
  Clang_Sema
  Clang_Serialization
  Clang_StaticAnalyzer_Core
  Clang_Tooling -> Clang_ToolingCore

Now, the module Clang_Format depends on;

  Clang_AST
  Clang_Basic
  Clang_ToolingCore

If the access relation's domain is empty, the access will never be
executed. We can just remove it.

We only remove write accesses. Partial read accesses are not yet
supported and instructions in the statement might require the
llvm::Value holding the read's result to be defined.

Change the indention of the last brace to align with the opening line.

Before:

            Instructions {
                  %val = fadd double %arg, 2.100000e+01
                  store double %val, double* %A
                }

After:

            Instructions {
                  %val = fadd double %arg, 2.100000e+01
                  store double %val, double* %A
            }

Hoisted loads can be trivially supported because there are no
MemoryAccess to be modified, the loaded value is just available
at code generation.

llvm-svn: 308826

This pass 'forwards' operand trees into statements that use them in
order to avoid scalar dependencies.

This minimal implementation handles only the case of speculatable
instructions. We will successively add support for:
- Hoisted loads
- Read-only values
- Synthesizable values
- Loads
- PHIs
- Forwarding only parts of the tree

As discussed on llvm-dev I've implemented the first basic steps towards
llvm-objcopy/llvm-objtool (name pending).

This change adds the ability to copy (without modification) 64-bit
little endian ELF executables that have SHT_PROGBITS, SHT_NOBITS,
SHT_NULL and SHT_STRTAB sections.

Summary:
This is a pure refactoring change.  It just moves code that is
related to filesystem operations from sanitizer_common.{cc,h} to
sanitizer_file.{cc,h}.  This makes it cleaner to disable the
filesystem-related code for a new port that doesn't want it.

Submitted on behalf of Roland McGrath.

Targets.cpp is getting unwieldy, and even minor changes cause the entire thing 
to cause recompilation for everyone. This patch bites the bullet and breaks 
it up into a number of files.

I tended to keep function definitions in the class declaration unless it 
caused additional includes to be necessary. In those cases, I pulled it 
over into the .cpp file. Content is copy/paste for the most part, 
besides includes/format/etc.

MIR SRADI uses instruction template XSForm_1rc which declares Defs = [CARRY]. But MIR SRADI_32 uses instruction template XSForm_1, and it doesn't declare such implicit definition. With patch D33720 it causes wrong code generation for perl.
