Remove many of the overridden methods from toolchainBase in favor
of having smaller composable types. toolchainNoCrt, toolchain32Bit
and toolchain64Bit now only provide a few methods and can be mixed
in to any toolchain type. toolchainLinux, toolchainBionic,
toolchainWindows and toolchainDarwin now embed toolchainBase to provide
the default flags methods for when they don't override them.
This avoids the need for disambiguation methods required when a
type embeds two types that implement the same method.

We're now packaging llvm-windres (aosp/1870074) which can be used as a
substitute for GNU binutils' windres, but we've also removed the last
consumer of .rc files in aosp/1867048 (external/mdnsresponder/).
In the worst case, we can bring back support for .rc files but instead
process them with llvm-windres.

- Stop including libstdc++ headers.
- '-pthread' and 'static-libgcc' are unused when we pass -nodefaultlibs.
We didn't pass -nodefaultlibs for libstdc++.
- Use SjLj exceptions for 32-bit. libgcc_eh implements SjLj exception
model for 32-bit.
- Disable visibility annotations for libcxx and libcxxabi since we are
only going to support these as static libraries.
- Use Win32 threads. MinGW pthreads throws an error when building
libcxx since it's pthread_mutex_initializer is not constant (needs a
cast).
- Link libgcc_eh, which needs pthread, which in turn depends on
kernel32. Wrap the libraries with --start-group and --end-group and
remove duplicates.

Bug: http://b/113171785
From
https://android-review.googlesource.com/c/platform/system/core/+/737292:
The --dynamicbase linker flag enables use of Address Space Layout
Randomization (ASLR) on Windows Vista and newer. It causes the code
segment / module to be loaded at unpredictable addresses to make
exploits harder to construct.
The --nxcompat linker flag enables use of Data Execution Protection
(DEP) on Windows XP SP2 and newer. It causes the process to be killed if
the process tries to execute code on memory pages not marked executable.
This makes exploits harder to construct because the stack is then not
executable, other data pages aren't, etc.
These bits are already set on AdbWinApi.dll and AdbWinUsbApi.dll.
--high-entropy-va provides improved ASLR.

Bug: http://b/69970955
With the MinGW prebuilts update (http://aosp/709402), executables get a
runtime dependency on libgcc_s_sjlj-1.dll with both gcc and Clang.
Passing -static-libgcc removes this dependency and is a better option
than having to package an extra dll with executables.

* Use new lld's --pack-dyn-relocs=android.
* When lld does not work:
* In Android.mk files use LOCAL_USE_CLANG_LLD := false.
* In Android.bp files use use_clang_lld: false.

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.
