* USE_CLANG_LLD is unedefined in current builds.
* When USE_CLANG_LLD is defined to 'true' or '1',
use clang's lld instead of ld or ld.gold.
* When lld is enabled:
* ld-only flags are not passed to 'lld'.
* location_packer is disabled.
* 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.
* Only arm, arm64, x86, and x86_64_devices have LLD flags;
all other hosts and targets do not call lld yet.

These flags were added for gcc, but are always stripped out when
compiling for clang. Since gcc is barely used, removed them.

Move -fdata-sections and -fno-short-enums to global device flags.
-fdata-sections was not previously set on x86[_64], -fno-short-enums
was not previously set on mips[64].

to be set for x86[_64] too.

-Wl,-z,noexecstack
-Wl,-z,relro

-Wl,--warn-shared-textrel

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.

With the latest Clang we do not have issue with beqc instruction,
so allow generation of compact branches for mips.

Clang generates invalid beqc compact branch instruction. Disable
compact branch generation until clang is updated to include r278824,
which fixes the issue.
