772bb1ade3 Disable open flock flags on darwin 
The tests were put into a deadlock, and it seems that darwin doesn't
support `O_SYNC`, though it supports `O_NONBLOCK`. It shouldn't block
even with that, but I'm not sure why else it would fail.

d0d7895d33 Return error from else 
That removes the other switch cases (`error.WouldBlock` here) from the
error set, I think.

317f06dc77 Add lock_nonblocking flag for creating or opening files 
Also, make windows share delete access. Rationale: this is how it works
on Unix systems, mostly because locks are (usually) advisory on Unix.

117d15ed7a Fix file locking on windows 
The share_access bitfield was being ORed with what was supposed to be
parts of the default value, meaning that the share_access would be
more permissive than expected.

71c5aab3e7 Make lock option an enum 
For some reason, this breaks file locking on windows. Not sure if this is
a problem with wine.

cmake: improvements to cross-compiling for Windows 
* don't unconditionally pass -lz3 for mingw builds. If mingw builds
   require this then the llvm-config executable should put it as part of
   --system-libs. If there is a bug and it does not do that, and we need
   a workaround, then the workaround should be an explicit cmake option.
 * don't link libstage2.a against -lntdll. This causes zig to set
   `builtin.link_mode == .Dynamic` and include the TLS definitions,
   which then collide with the mingw-w64 symbols. This should probably
   be addressed separately, but for now this solves the problem and
   there is no reason to link a static library against a DLL.
 * Findllvm.cmake no longer treats the libraries as "optional" and will
   emit a cmake error if one is not found. Additionally, the
   not-required LLVM library LLVMTableGen is omitted.

libc_installation.zig: don't special-case based on C ABI 
Whether the C ABI is mingw-w64 or msvc, detection of native libc paths
should be the same. In the future we may want to allow passing a C ABI
parameter to detectNativeCPaths() but for now we have the same behavior
regardless.

build.zig supports specifying config.h location explicitly 
also it does not try to run llvm-config executable when -Dlib-files-only

This fixes cross-compiling using the bootstrap repository.

a0b73c9f02 compiler-rt: Separate max size allowed for load/store and CAS 
The v6m ISA has no way to express a CAS loop natively without turning
off the interrupts or using the kernel cmpxchg harness.

On such a platform the user has to provide a few __sync_* builtins to
satisfy the linker.

type_has_one_possible_value takes comptime struct fields into account 
Before, type_has_one_possible_value would return false for the value
`.{1}`. But actually, that type is a tuple with a single comptime field.
Such a type, in fact, has one possible value.

This plus the corresponding adjustment to get_the_one_possible_value
solves #3878.
