[vm] Unify function prologue generation across all backends.

Previously we would generate the prologue in FunctionEntryInstr or OsrEntryInstr
on X64/ARM, and in CompileGraph on ARM64/IA32/DBC. This caused a confusing asymmetry
in the code.

Now we generate it in FunctionEntryInstr/OsrEntryInstr on all backends.

Partially addresses dartbug.com/34162.

This also fixes a regression on a protobuf benchmark due to ICDatas not being saved.
