Todd Fiala 3452df6723 Fixed b18655: cleaned up script interpreter file reference handling.
This change addresses shutdown crashes in the python lldb module when
the script interpreter was hanging on to saved file references after
leaving a session.  It also gets rid of extra references to the
stdin/stdout/stderr python file objects that are created when entering
the session.

This change also moves the bundled pyexpect 2.4 library to the front
of the python library path so that a python distribution default
pyexpect (2.3 in Ubuntu 12.04) is not picked up first.

Renato Golin 9b37d35051 Comment out unused macro because of warning
Modern compilers (Clang 3.4, GCC 4.8) warn on variadic macros being
introduced in C99, which produces a huge number of useless diagnostics
since this macro is unused in the whole project.

Saleem Abdulrasool 4c4789be5e ARM IAS: support .object_arch
The .object_arch directive indicates an alternative architecture to be specified
in the object file.  The directive does *not* effect the enabled feature bits
for the object file generation.  This is particularly useful when the code
performs runtime detection and would like to indicate a lower architecture as
the requirements than the actual instructions used.

Saleem Abdulrasool 5d962d31f1 ARM IAS: support .movsp

Saleem Abdulrasool 56e06e8640 ARM: suuport .tlsdescseq directive
This enhances the ARMAsmParser to handle .tlsdescseq directives.  This is a
slightly special relocation.  We must be able to generate them, but not consume
them in assembly.  The relocation is meant to assist the linker in generating a
TLS descriptor sequence.  The ELF target streamer is enhanced to append
additional fixups into the current segment and that is used to emit the new
R_ARM_TLS_DESCSEQ relocations.

Saleem Abdulrasool a3f12bdeec ARM: support TLS descriptor relocations
Add support for tlsdesc relocations which are part of the ABI, marked as
experimental.  These relocations permit the linker to perform TLS reference
optimizations.

Saleem Abdulrasool 6e00ca887e ARM: support tlscall relocations
This adds support for TLS CALL relocations.  TLS CALL relocations are used to
indicate to the linker to generate appropriate entries to resolve TLS references
via an appropriate function invocation (e.g. __tls_get_addr(PLT)).

In order to accomodate the linker relaxation of the TLS access model for the
references (GD/LD -> IE, IE -> LE), the relocation addend must be incomplete.
This requires that the partial inplace value is also incomplete (i.e. 0).  We
simply avoid the offset value calculation at the time of the fixup adjustment in
the ARM assembler backend.

Rafael Espindola 5e812afaeb Simplify the handling of iterators in ObjectFile.
None of the object file formats reported error on iterator increment. In
retrospect, that is not too surprising: no object format stores symbols or
sections in a linked list or other structure that requires chasing pointers.
As a consequence, all error checking can be done on begin() and end().

This reduces the text segment of bin/llvm-readobj in my machine from 521233 to
518526 bytes.

John McCall 2575d88059 Diagnose typedef names for linkage purposes that would change
a previously-computed linkage as an unsupportable error condition.

Per discussion on cfe-commits, this appears to be a
difficult-to-resolve flaw in our implementation approach;
we may pursue this as a language defect, but for now it's
better to diagnose it as unsupported than to produce
inconsistent results (or assertions).  Anything that we can
do to limit how often this diagnostic fires, such as the
changes in r200380, is probably for the best, though.
