1ad25cdc99 termios.h contains the winsize structure we need to determine the 
width of a terminal. Don't try to get the width of a terminal if we
don't have this header.

consistency with other routines that use a null Loop* to mean code

573333530f Tweak MemoryBuffer::getSTDIN so that it returns after the first EOF. 
It doesn't matter for piped input, but it's annoying when typing at the

fa57451cf5 Help DejaGnu avoid pipe-jam by producing less output from certain test cases. 
When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.

94c30c8409 Pass to verify generated machine code. 
The following is checked:

* Operand counts: All explicit operands must be present.

* Register classes: All physical and virtual register operands must be
  compatible with the register class required by the instruction descriptor.

* Register live intervals: Registers must be defined only once, and must be
  defined before use.

The machine code verifier is enabled with the command-line option
'-verify-machineinstrs', or by defining the environment variable
LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the
verifier errors.

5fe69fa68e Split out the Dwarf writer stuff into separate files. This is a much more 
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!
