031d30781a Use GZIPBIN instead of GZIP. Apparently gzip uses GZIP as an environment 
variable for args you want to default pass to gzip.

Patch based on one by asau@inbox.ru.

Fixes PR8758.

2ea8ee7c76 Formalize the notion that AVX and SSE are non-overlapping extensions from the compiler's point of view. Per email discussion, we either want to always use VEX-prefixed instructions or never use them, and are taking "HasAVX" to mean "Always use VEX". Passing -mattr=-avx,+sse42 should serve to restore legacy SSE support when desirable.

05018c2f28 Fix an issue in some Thumb fixups, where the effective PC address needs to be 4-byte aligned when calculating 
the offset.  Add a new fixup flag to represent this, and use it for the one fixups that I have a testcase for needing
this.  It's quite likely that the other Thumb fixups will need this too, and to have their fixup encoding logic
adjusted accordingly.

193c3acbe5 Add support for parsing ARM arithmetic instructions that update or don't update 
the condition codes.  Where the ones that do have an 's' suffix and the ones
that don't don't have the suffix.  The trick is if MatchInstructionImpl() fails
we try again after adding a CCOut operand with the correct value and removing
the 's' if present.  Four simple test cases added for now, lots more to come.

c6f9261711 ARM stm/ldm instructions require more than one register in the register list.

0e1fb7afcc Add a license comment to the generated arm_neon.h header. 
Remove the previous header.  I don't think we need to expose to end users
that we use TableGen to produce our version of arm_neon.h, and that header
was also using doubleslash comments which could be a problem when using it
in strict C89 compilations.
