[compiler-rt] Introduce the notion of an interceptor trampoline
To make the interceptor implementation more flexible, allowing for 2
levels of indirection instead of just 1 in the current scheme (where the
intercepted function aliases the interceptor implementation), introduce
the notion of an interceptor "trampoline".
A trampoline may be a real function (and not just an alias, where
aliases of aliases do not work), which will simply forward to the
interceptor implementation; the intercepted function will then alias the
trampoline:
func -[alias]-> trampoline -[call]-> interceptor
Make the necessary changes to prepare for introducing real trampolines.
This change does not yet introduce any real trampolines, and so
trampoline == interceptor, and we currently still just have:
func -[alias]-> interceptor
NFC.

[sanitizer] Define SANITIZER_GLIBC to refine SANITIZER_LINUX feature detection and support musl
Several `#if SANITIZER_LINUX && !SANITIZER_ANDROID` guards are replaced
with the more appropriate `#if SANITIZER_GLIBC` (the headers are glibc
extensions, not specific to Linux (i.e. if we ever support GNU/kFreeBSD
or Hurd, the guards may automatically work)).
Several `#if SANITIZER_LINUX && !SANITIZER_ANDROID` guards are refined
with `#if SANITIZER_GLIBC` (the definitions are available on Linux glibc,
but may not be available on other libc (e.g. musl) implementations).
This patch makes `ninja asan cfi lsan msan stats tsan ubsan xray` build on a musl based Linux distribution (apk install musl-libintl)
Notes about disabled interceptors for musl:
* `SANITIZER_INTERCEPT_GLOB`: musl does not implement `GLOB_ALTDIRFUNC` (GNU extension)
* Some ioctl structs and functions operating on them.
* `SANITIZER_INTERCEPT___PRINTF_CHK`: `_FORTIFY_SOURCE` functions are GNU extension
* `SANITIZER_INTERCEPT___STRNDUP`: `dlsym(RTLD_NEXT, "__strndup")` errors so a diagnostic is formed. The diagnostic uses `write` which hasn't been intercepted => SIGSEGV
* `SANITIZER_INTERCEPT_*64`: the `_LARGEFILE64_SOURCE` functions are glibc specific. musl does something like `#define pread64 pread`
* Disabled `msg_iovlen msg_controllen cmsg_len` checks: musl is conforming while many implementations (Linux/FreeBSD/NetBSD/Solaris) are non-conforming. Since we pick the glibc definition, exclude the checks for musl (incompatible sizes but compatible offsets)
Pass through LIBCXX_HAS_MUSL_LIBC to make check-msan/check-tsan able to build libc++ (https://bugs.llvm.org/show_bug.cgi?id=48618).
Many sanitizer features are available now.
