Use GET_CURRENT_FRAME() to calculate the memory layout for power. This works
...
for both PPC64 Big and Little endian modes, so also eliminates the need for
the BIG_ENDIAN/LITTLE_ENDIAN #ifdeffery.
By trial and error, it also looks like the kPPC64_ShadowOffset64 value is
valid using (1ULL << 41) for both BE and LE, so that #if/#elif/#endif block
has also been simplified.

[compiler-rt] Enable ASAN for powerpc64le-linux
...
Whitespace update for lint check by myself (Will). Otherwise code and comments by Peter Bergner, as previously seen on llvm-commits.
The following patch gets ASAN somewhat working on powerpc64le-linux.
It currently assumes the LE kernel uses 46-bit addressing, which is
true, but it doesn't solve the case for BE where it may be 44 or
46 bits. That can be fixed with a follow on patch.
There are some test suite fails even with this patch that I haven't had
time to solve yet, but this is better than the state it is in now.
The limited debugging of those test suite fails seems to show that the
address map for 46-bit addressing has changed and so we'll need to
modify the shadow memory location slightly. Again, that can be fixed
with a follow on patch.

[asancov] Write coverage directly to a memory-mapped file.

This way does not require a __sanitizer_cov_dump() call. That's
important on Android, where apps can be killed at arbitrary time.
We write raw PCs to disk instead of module offsets; we also write
memory layout to a separate file. This increases dump size by the
factor of 2 on 64-bit systems.

Before, we had an unused internal_getpid function for Linux, and a

renamed to internal_getpid, bringing the Linux variant into use.

[nolibc] Change internal syscall API to remove reliance on libc's errno.

This change moves to a model where the error value of a system call is
potentially contained in the return value itself rather than being
implicit in errno. The helper function internal_iserror can be used
to extract the error value from a return value. On platforms other
than Linux/x86_64 this still uses errno, but other platforms are free
to port their error handling to this new model.
