Make improvements This change progresses our AARCH64 support: - The AARCH64 build and tests are now passing - Add 128-bit floating-point support to printf() - Fix clone() so it initializes cosmo's x28 TLS register - Fix TLS memory layout issue with aarch64 _Alignas vars - Revamp microbenchmarking tools so they work on aarch64 - Make some subtle improvements to aarch64 crash reporting - Make kisdangerous() memory checks more accurate on aarch64 - Remove sys_open() since it's not available on Linux AARCH64 This change makes general improvements to Cosmo and Redbean: - Introduce GetHostIsa() function in Redbean - You can now feature check using pledge(0, 0) - You can now feature check using unveil("",0) - Refactor some more x86-specific asm comments - Refactor and write docs for some libm functions - Make the mmap() API behave more similar to Linux - Fix WIFSIGNALED() which wrongly returned true for zero - Rename some obscure cosmo keywords from noFOO to dontFOO 2023-06-03 15:12:13 +00:00			`#include "libc/runtime/fenv.h"`
