Rollup merge of #140758 - dpaoliello:armhazard, r=jieyouxu
[win][arm64] Disable MSVC Linker 'Arm Hazard' warning While trying to get the aarch64-msvc build working correctly (#140136), I observed the following test failure: From <https://github.com/rust-lang/rust/pull/140136#issuecomment-2848179657> ``` = note: main.main.d17f5fbe6225cf88-cgu.0.rcgu.o : fatal error LNK1322: cannot avoid potential ARM hazard (Cortex-A53 MPCore processor bug #843419) in section 0x57; please consider using compiler option /Gy if it was not used ``` This is warning of a code sequence that triggers a bug in Cortex-A53 processors: <https://developer.arm.com/documentation/epm048406/latest> However, since Windows 10 isn't supported on the Cortex-A53, this warning is not required, so it can be suppressed using the undocumented `/arm64hazardfree` flag.
