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.

0512be227c compiler-rt: Fix __floatunditf 
This builtin converts a u64 into a f128, not a u128 into a f128.

Fixes some weird-ass crashes that happened only on AArch64 systems.

Merge remote-tracking branch 'origin/llvm10'

7aac21c6f5 allow _ separators in number literals (stage 1) 
* Underscores `_` may be placed between two digits in a int/float literal
* Consecutive underscores are not allowed
* Fixed parsing bug in exponents of hexadecimal float literals.
  Exponents should always be base 10, but hex characters would be parsed
  inside the exponent and everything after them would be ignored. eg:
  `0x1.0p1ab1` would be parsed as `0x1.0p1`.

introduce operating system version ranges as part of the target 
* re-introduce `std.build.Target` which is distinct from `std.Target`.
   `std.build.Target` wraps `std.Target` so that it can be annotated as
   "the native target" or an explicitly specified target.
 * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a
   struct which has the tag as well as version range information.
 * `std.elf` gains some more ELF header constants.
 * `std.Target.parse` gains the ability to parse operating system
   version ranges as well as glibc version.
 * Added `std.Target.isGnuLibC()`.
 * self-hosted dynamic linker detection and glibc version detection.
   This also adds the improved logic using `/usr/bin/env` rather than
   invoking the system C compiler to find the dynamic linker when zig
   is statically linked. Related: #2084
   Note: this `/usr/bin/env` code is work-in-progress.
 * `-target-glibc` CLI option is removed in favor of the new `-target`
   syntax. Example: `-target x86_64-linux-gnu.2.27`

c86589a738 disable f128 compiler_rt tests failing on windows 
These were never working with native CPU features. In this branch,
we fix native CPU features not being enabled on Windows, and regress
f128 language features. In the llvm10 branch, all this is fixed,
and the tests are re-enabled.
