Log:
Unify changes with Android's GCC 4.9 compiler.

Add the following changes from the Android
GCC 4.9 compiler (mostly adding fixes for aarch64):

Fix mingw build breakage
    1) Add missing _GCOV_fopen if !__KERNEL__
    2) Use _fullpath

Backport Cortex-A57's machine description support from trunk

Adjust generic move costs for aarch64. Backport from trunk

Enable C++ exceptions and RTTI by default.

Modify LINK_SPEC to pass --fix-cortex-a53-843419 as default

Rename libstdc++.so to libgnustl_shared.so when enabling bionic libs.

Drop mips64r2 from Android compiler's multilib

Merge "Drop mips64r2 from Android compiler's multilib"

Adjust several costs for AArch64:
  Refactor aarch64_address_costs; add cost tables for Cortex-A7;
  better estimate cost of building a constant; wrap aarch64_rtx_costs
  to dump verbose output; factor out common MULT cases; det default
  costs and handle vector modes; cost memory accesses using address
  costs; better cost logical operations; improve costs for div/mod and
  sign/zero extend operations; cost comparisons, flag setting
  operators and IF_THEN_ELSE; cost more Floating point RTX; cost
  TRUNCATE, SET, SYMBOL_REF, HIGH and LO_SUM; dump a message if we are
  unable to cost an insn; fix typos in cost data structure.


Add several improvements for AArch64 (Backported from GCC 5):
  (spill code - swap order in shr patterns; spill code - swap order in
  shl pattern; fix aarch64_rtx_costs of PLUS/MINUS; cost operand 0 in
  FP compare-with-0.0 case; properly cost FABD pattern; properly
  handle mvn-register and add EON+shift pattern and cost
  appropriately).

Disable inlining of memcpy for x86 with 'rep movs'.
Default to TLS guard for x86 stack-protector.
Change gcc BASE-VER from 4.9.x-google to 4.9.x

Cherry pick the following fixes from trunk: PR bootstrap/66638, 67954
(svn rev 230894, PR tree-optimization/65447,
PR tree-optimization/52563, tree-optimization/62173,
PR tree-optimization/48052, PR 64878, PR65048, PR65177, PR65735.

Port revision 219584 from linaro/gcc-4_9-branch

Fix for arm64 bad code for copysignl.
