[jdk21u-dev] RFR: 8335662: [AArch64] C1: guarantee(val < (1ULL << nbits)) failed: Field too big for insn

[Dmitry Chuyko]

This a clean backport of a small instruction encoding fix in LIR_Assembler::osr_entry() for aarch64. Without the fix the JVM can fail during OSR in C1. The bug was originally fixed in JDK 24 so I intend to integrate the backport only after JDK 24 is released. After jdk21u I'd like to proceed with jdk17u.

Testing: tier1,2 on linux-aarch64. The new test fails on current jdk21u and passes after patching.
