Merge System into Support.

Use the expanded form of S_ISREG. Hopefully this unbreaks the MSVC build.

Don't test isRegularFile before calling eraseFromDisk, since
eraseFromDisk does the same check. This avoids a stat call
in the common case.

Driver: Eliminate PipedJob, which is now unused.

llvm-svn: 110014

Driver: Add an explicit argument translation phase to the driver itself. We are going to need this to handle things like -Xassembler, -Xpreprocessor, and -Xlinker which we might have to introspect.

Driver: Mark some Compilation members const.

Driver: Move Compilation::Execute to Driver::ExecuteCompilation.
- The Compilation is just a helper class, it shouldn't have that amount of
logic in it.

Driver: Improve diagnostics for failed commands.
- Not all tools give good error messages, and sometimes the tool can fail w/o
any error (for example, when signalled).

- We suppress this message when the failing command is the compiler and it
failed normally (exit code == 1), under the assumption that it gave a good
diagnostic.

For example, for a linker failure we now get:
--
ddunbar@lordcrumb:tmp$ clang a.c b.c
ld: duplicate symbol _x in /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-bXYITq.o and /var/folders/cl/clrOX6SaG+moCeRKEI4PtU+++TI/-Tmp-/cc-6uK4jD.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--

For a compiler crash we get:
--
ddunbar@lordcrumb:tmp$ clang t.i
Assertion failed: (CGT.getTargetData().getTypeAllocSizeInBits(STy) == RL.getSize()), function layoutStructFields, file CodeGenTypes.cpp, line 573.
0 clang-cc 0x0000000100f1f1f1 PrintStackTrace(void*) + 38
... stack trace and virtual stack trace follow ...
clang: error: compiler command failed due to signal 6 (use -v to see invocation)
--

But for a regular compilation failure we get the usual:
--
ddunbar@lordcrumb:tmp$ clang c.c
c.c:1:6: error: invalid token after top level declarator
int x
^
1 diagnostic generated.
--

- No test case, not amenable to non-executable testing. :/

Driver: Prep for tool chain specific argument translation.
- Lift ArgList to a base class for InputArgList and DerivedArgList.

- This is not a great decomposition, but it does embed the
translation into the type system, and keep things efficient for
tool chains that don't want to do any translation.

- No intended functionality change.

Eventually I hope to get rid of tool chain specific translation and
have each tool do the right thing, but for now this is the easiest way
to match gcc precisely (which is good for testing).
