0.10.1

LLVM 15.0.7

This release of Zig upgrades to LLVM 15.0.7 which fixed a handful of bugs, \ 
including regressions introduced in LLVM 15.0.0. At time of writing, this \ 
hyperlink 404s because LLVM project did not provide release notes for this \ 
version.

Compiler

cmake: move 'continue' statement to avoid cmake bug
C backend: improve support for non-native float types
C backend: enough fixes for compiler to to be able to build itself
C backend: include zig.h with quotes instead of angle brackets.
C backend: remove redundant definition of u16/i16 in zig.h
C backend: fixed some C warnings and errors on gcc 11.3.0.
c backend: Output string literals for array init of bytes
Fixed typo in zig.h causing incorrect behavior.
LLVM: mangle extern function names for Wasm target
Fixed detection of MSVC installation on aarch64-windows.
Fixed comptime array initialization.

known similar performance regression that is not fixed in 0.10.1.

LLVM: fix canElideLoad behavior with loops
Improved error messages.
Fixed false positive dependency loops.
Sema: resolve elem type for non-default aligned ptrs
Compilation: fixed deadlock when compiling the same C source file twice
Fixed compiler crashes.
mingw: add missing vscprintf.c file
LLVM: Respect alignment for `.union_init`
Ensure f128 alignment matches c_longdouble alignment
Support modifiers in inline assembly.
Fixes bug in AVR codegen for LLVM backend
Fixed compilation not failing when there are linker errors.
cache: Fix LockViolation during C compilation paths
Fix another LockViolation case on Windows

Sema: fix missing struct layout for llvm backend
Miscellaneous fixes to the experimental ARM and aarch64 backends.
cli: set sysroot when --sysroot option was passed
macho: do not zero-out file if there are no nonzerofill sects
macho: parse weak imports in tbd descriptors
fixes to the DWARF parser

Improve aarch64 feature detection based on the readouts from privileged system \ 
registers

macho: add missing defs of compact unwind info records
Bug fix: Prevent uninitialized parse nodes
Sema: resolve lazy align in zirReify for union fields
llvm codegen: fix f16,f32,f64 nan bitcasts

macos: enable -headerpad_max_install_names
Translate-C Remainder Macro Fix
Many compiler crashes are fixed.
Many compile error messages are more helpful.

windows: fix _tls_index not being defined if libc wasn't linked, and fix x86 \ 
name mangling
