linkonce_odr_auto_hide was in incomplete attempt to implement a way
for the linker to hide symbols that are known to be available in every
TU and whose addresses are not relevant for a particular DSO.

It was redundant in that it all its uses are equivalent to
linkonce_odr+unnamed_addr. Unlike those, it has never been connected
to clang or llvm's optimizers, so it was effectively dead.

Given that nothing produces it, this patch just nukes it
(other than the llvm-c enum value).

These used to be referenced by the CGI->AWI map (in AsmWriterEmitter), but
stored in a vector local to EmitPrintInstruction. Move the vector to
AsmWriterEmitter too.

The error raised by Python varies by platform(!), so let's just catch any
exception and fall back.

Thanks to Sylvestre Ledru for noticing this on a Debian / Python 2.7 system
running code coverage.

so try PATH next. Assume it is sane enough to cover the usual system
bash locations too, but the old list is not good enough for NetBSD.

If multiprocessing was requested, detected as available and subsequently failed
to initialize it's worth letting the user know about it before falling back to
threads.

This condition can arise in certain OpenBSD / FreeBSD Python versions.

llvm-svn: 193465

Some versions of Python on the builders seem strict about this.

llvm-svn: 193464

This should be a better fix for lit multiprocessing failures, replacing the
OpenBSD and FreeBSD workarounds in r193413 and r193457.

Speculative quick fix based on clang-X86_64-freebsd output:

  File "/usr/local/lib/python2.6/multiprocessing/synchronize.py", line 33, in <module>
    " function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

 - This was never a big win, and is irrelevant now that we commonly use
   multiprocessing based parallelism.

Allow pinsrw/pinsrb/pextrb/pextrw/movmskps/movmskpd/pmovmskb/extractps instructions to parse either GR32 or GR64 without resorting to duplicating instructions.

Really fix CHECK-LABEL and CHECK-DAG interaction. This actually just restores the initial implementation that was in r186162 but got lost in some subsequent refactoring. More explicit variable names and comments are present now to hopefully prevent repeat regression, as well as another test.

Remove unneeded MMX instruction definition by moving pattern to an equivalent instruction definition and removing the filtering from the disassembler table building.

llvm-svn: 192175

Remove some instructions that existed to provide aliases to the assembler. Can be done with InstAlias instead. Unfortunately, this was causing printer to use 'vmovq' or 'vmovd' based on what was parsed. To cleanup the inconsistencies convert all 'vmovd' with 64-bit registers to 'vmovq', but provide an alias so that 'vmovd' will still parse.

llvm-svn: 192171

Remove some instructions that seem to only exist to trick the filtering checks in the disassembler table creation. Just fix up the filter to let the real instruction through instead.

This reverts commit r192070 which reverted r192069, I forgot to
regenerate the configure scripts.
