8c96862847 Modernize raw_fd_ostream's constructor a bit. 
Take a StringRef instead of a "const char *".
Take a "std::error_code &" instead of a "std::string &" for error.

A create static method would be even better, but this patch is already a bit too
big.

2559070422 Introduce a string_ostream string builder facilty 
string_ostream is a safe and efficient string builder that combines opaque
stack storage with a built-in ostream interface.

small_string_ostream<bytes> additionally permits an explicit stack storage size
other than the default 128 bytes to be provided. Beyond that, storage is
transferred to the heap.

This convenient class can be used in most places an
std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair
would previously have been used, in order to guarantee consistent access
without byte truncation.

The patch also converts much of LLVM to use the new facility. These changes
include several probable bug fixes for truncated output, a programming error
that's no longer possible with the new interface.

5f4aba6c8a raw_ostream::operator<<(StringRef): Avoid potential overflow in pointer arithmetic. 
(OutBufCur + Size) might overflow if Size were large. For example on i686-linux,

  OutBufCur: 0xFFFDF27D
  OutBufEnd: 0xFFFDF370
  Size:      0x0002BF20 (180,000)

It caused flaky error in MC/COFF/section-name-encoding.s.
