Remove another hasRawTextSupport.

To remove this one simply move the end of file logic from the asm printer to
the target mc streamer.

This removes the last call to hasRawTextSupport from lib/Target.

Remove a redundant call to hasRawTextSupport.

The code path it was guarding was already using emitRawComment.

Split out small-code-model MCJIT testcase in order to xfail for AArch64, where
PC-rel relocations aren't yet fully implemented.

Don't put non-static allocas in the static alloca map

Allocas marked inalloca are never static, but we were trying to put them
into the static alloca map if they were in the entry block.  Also add an
assertion in x86 fastisel.

Introduce llvm::sys::path::home_directory.

This will be used by the line editor library to derive a default path to
the history file.

Introduce line editor library.

This library will be used by clang-query. I can imagine LLDB becoming another
client of this library, so I think LLVM is a sensible place for it to live.
It wraps libedit, and adds tab completion support.

The code is loosely based on the line editor bits in LLDB, with a few
improvements:

 - Polymorphism for retrieving the list of tab completions, based on
   the concept pattern from the new pass manager.

 - Tab completion doesn't corrupt terminal output if the input covers
   multiple lines. Unfortunately this can only be done in a truly horrible
   way, as far as I can tell. But since the alternative is to implement our
   own line editor (which I don't think LLVM should be in the business of
   doing, at least for now) I think it may be acceptable.

 - Includes a fallback for the case where the user doesn't have libedit
   installed.

Note that this uses C stdio, mainly because libedit also uses C stdio.

Implement inalloca codegen for x86 with the new inalloca design

Calls with inalloca are lowered by skipping all stores for arguments
passed in memory and the initial stack adjustment to allocate argument
memory.

Now the frontend is responsible for the memory layout, and the backend
doesn't have to do any work.  As a result these changes are pretty
minimal.
