Indu Bhagat c7defc5386 gas: x86: synthesize CFI for hand-written asm 
This patch adds support in GAS to create generic GAS instructions
(a.k.a., the ginsn) for the x86 backend (AMD64 ABI only at this time).
Using this ginsn infrastructure, GAS can then synthesize CFI for
hand-written asm for x86_64.

A ginsn is a target-independent representation of the machine
instructions.  One machine instruction may need one or more ginsn.

This patch also adds skeleton support for printing ginsn in the listing
output for debugging purposes.

Since the current use-case of ginsn is to synthesize CFI, the x86 target
needs to generate ginsns necessary for the following machine
instructions only:

 - All change of flow instructions, including all conditional and
   unconditional branches, call and return from functions.
 - All register saves and unsaves to the stack.
 - All instructions affecting the two registers that could potentially
   be used as the base register for CFA tracking.  For SCFI, the base
   register for CFA tracking is limited to REG_SP and REG_FP only for
   now.

The representation of ginsn is kept simple:

- GAS instruction has GINSN_NUM_SRC_OPNDS (defined to be 2 at this time)
  number of source operands and one destination operand at this time.
- GAS instruction uses DWARF register numbers in its representation and
  does not track register size.
- GAS instructions carry location information (file name and line
  number).
- GAS instructions are ID's with a natural number in order of their
  addtion to the list.  This can be used as a proxy for the static
  program order of the corresponding machine instructions.

Note that, GAS instruction (ginsn) format does not support
GINSN_TYPE_PUSH and GINSN_TYPE_POP.  Some architectures, like aarch64,
do not have push and pop instructions, but rather STP/LDP/STR/LDR etc.
instructions.  Further these instructions have a variety of addressing
modes, like offset, pre-indexing and post-indexing etc.  Among other
things, one of differences in these addressing modes is _when_ the addr
register is updated with the result of the address calculation: before
or after the memory operation.  To best support such needs, the generic
instructions like GINSN_TYPE_LOAD, GINSN_TYPE_STORE together with
GINSN_TYPE_ADD, and GINSN_TYPE_SUB may be used.

The functionality provided in ginsn.c and scfi.c is compiled in when a
target defines TARGET_USE_SCFI and TARGET_USE_GINSN.  This can be
revisited later when there are other use-cases of creating ginsn's in
GAS, apart from the current use-case of synthesizing CFI for
hand-written asm.

Support is added only for System V AMD64 ABI for ELF at this time.  If
the user enables SCFI with --32, GAS issues an error:

  "Fatal error: SCFI is not supported for this ABI"

For synthesizing (DWARF) CFI, the SCFI machinery requires the programmer
to adhere to some pre-requisites for their asm:
   - Hand-written asm block must begin with a .type   foo, @function
It is highly recommended to, additionally, also ensure that:
   - Hand-written asm block ends with a .size foo, .-foo

The SCFI machinery encodes some rules which align with the standard
calling convention specified by the ABI.  Apart from the rules, the SCFI
machinery employs some heuristics.  For example:
   - The base register for CFA tracking may be either REG_SP or REG_FP.
   - If the base register for CFA tracking is REG_SP, the precise amount of
     stack usage (and hence, the value of REG_SP) must be known at all times.
   - If using dynamic stack allocation, the function must switch to
     FP-based CFA.  This means using instructions like the following (in
     AMD64) in prologue:
        pushq   %rbp
        movq    %rsp, %rbp
     and analogous instructions in epilogue.
   - Save and Restore of callee-saved registers must be symmetrical.
     However, the SCFI machinery at this time only warns if any such
     asymmetry is seen.

These heuristics/rules are architecture-independent and are meant to
employed for all architectures/ABIs using SCFI in the future.
