Add -Wimplicit-fallthrough checks if supported
...
Clang since r369414 (clang-10) can now check -Wimplicit-fallthrough for
C code, and use the GNU C style attribute to denote fallthrough.
Move the test from header only to autoconf. The previous test used
brittle version detection which did not work for newer clang that
supported this feature.
The attribute has to be its own statement, hence the added `;`. It also
can only precede case statements, so the final cases should be
explicitly terminated with break statements.

some architecture like AArch64 may not have the open syscall, but have
openat syscall. so check and use SYS_openat if SYS_openat available if
SYS_open is not supported at init_thp_state.

Optimize cache_bin_alloc_easy for malloc fast path
...
`tcache_bin_info` is not accessed on malloc fast path but the
compiler reserves a register for it, as well as an additional
register for `tcache_bin_info[ind].stack_size`. The optimization
gets rid of the need for the two registers.

Suppress tdata creation in reentrancy
...
This change suppresses tdata initialization and prof sample threshold
update in interrupting malloc calls. Interrupting calls have no need
for tdata. Delaying tdata creation aligns better with our lazy tdata
creation principle, and it also helps us gain control back from
interrupting calls more quickly and reduces any risk of delegating
tdata creation to an interrupting call.
