-fomit-frame-pointer was only being set for arm and mips. Since
we always use unwind tables and not frame pointers to unwind, and
since ART generated code does not use frame pointers, just turn
off frame pointers everywhere to gain an extra register.

When the following lines are specified in the BoardConfig.mk
TARGET_2ND_ARCH_VARIANT := armv8-a
TARGET_2ND_CPU_VARIANT := generic
The resulted binaries won't be built using 32-bit armv8-a integer
division instructions. Instead, division routines are used because
the build system will set a compiler option "-march=armv7-a", and
hence overwiting the previous "-march=armv8-a", when
TARGET_2ND_CPU_VARIANT is set to generic (or unset).
Bug: 67446726
Test: lunch aosp_arm64; make -j; emulator # boot to home screen
Also verify -march=armv7-a is not specified in the compiler
command line and the resulted binary actually uses integer
division instructions.

there's no use case for prepending/appending to bool, and string
properties within module struct. Declearing "*bool" and "*string" almost
cover everything user need.
I did see one case that user specify relative_install_path as
path prefix in cc_defaults, and concatenate with the one in real module
to get the final relative install path in Android.bp <bionic/tests/libs>.

-fno-canonical-system-headers is required for gcc to use relative

* changes:
Remove no_default_compiler_flags property
Move -fomit-frame-pointer to armCflags
Consolidate ldflags that are used on all devices
Remove -Wl,--gc-sections from target flags
Consolidate cflags that are set on all devices
Consolidate global cflags
no_default_compiler_flags is only used by the crt* modules,
is unnecessary, and causes problems when necessary flags like
-no-canonical-prefixes are not passed. Remove the property.
Use useVndk() instead of noDefaultCompilerFlags() to determine
if adding libc as a dependency is necessary and won't cause a
circular dependency.

Move all the flags that are used everywhere (or should be used
everywhere) into cc/config/global.go:
-no-canonical-prefixes
-fno-exceptions
-Wno-multichar
-O2
-g
-fno-strict-aliasing
Also remove flags that are already in noOverrideGlobalCflags:
-Werror=pointer-to-int-cast
-Werror=int-to-pointer-cast
x86 and x86_64 were specifying -fstrict-aliasing, but that was
being overriden later by -fno-strict-aliasing, so remove it.
ARM devices still override -fno-strict-aliasing to -fstrict-aliasing
when using ARM (vs. Thumb) instruction set.

Convert abi warnings to errors by removing the -advice-only flag from
the invocation of header-abi-diff. This will only apply to branches with
reference abi dumps checked into prebuilts/abi-dumps/(v)ndk (since
abi-diffing will only be triggered on them.)
Also allow for:
1) Extensions.
2) Changes to types in exported headers, unreferenced by public symbols still
trigger warnings.
3) Any removal of symbols appearing in a shared library's .dynsym table, but not
in exported headers is still a warning.
