Thomas Preud'homme 4d354d8b89 [ARM] Clean up selection of feature bits 
I've always found the code in ARM backend of gas to control what
CPU/architecture and FPU are selected by the user and to support
autodetection of features complex and confusing. Chief among the
issues I have with that code is the lack of comments to explain
the meaning of the various variables. This patch addresses that
and much more:

- add comments to explain meaning of all arm_feature_set variables
- keep track of currently selected CPU, extensions and FPU in a separate
  set of new variables
- make naming of variable more consistent
- remove dead code
- simplify handling of extensions

The overall approach is as follows:

* restrict m*_opt variable to hold the feature bits of the
  corresponding mcpu/march/mfpu command-line options
* record selected CPU, extensions and FPU in new selected_* during
  md_begin
* whenever a .cpu/.arch/.arch_extension/.fpu directive is met, update
  the corresponding selected_* variables (eg. selected_arch, then
  selected_cpu for a .cpu or .arch directive) and then finally
  cpu_variant from them
* pass extension feature set pointer by value to arm_parse_extension
  since it's only ever called from arm_parse_cpu and arm_parse_arch
  which allocate the extension feature set themselves
* likewise, remove allocation from s_arm_arch_extension since the use
  of arm_feature_set structure for selected_ext rather than a pointer
  alleviate the need for it
* in autodetection mode, only set all CPU fits in cpu_variant but leave
  selected_cpu* variables unset
* in md_begin, remove dead "else if" to set a default FPU when no FPU
  was selected. Setting a default FPU based on CPU as did the code
  before it turn dead should be based on the default FPU field of the
  CPU and architecture table as will be done in a separate patch. Logic
  is wrong anyway since it sets VFP2 as default FPU for Armv6-M and
  Armv7-M

Hopefully that should be enough to understand the change but if not feel
free to ask questions about the patch. While I believe the new code is
easier to understand, it remains complex and the old one was even more
complex so the change is difficult to understand.
