  -----------
  [AMDGPU] Extend SRA i64 simplification for shift amts in range [33:62] (#138913)

Extend sra i64 simplification to shift constants in range [33:62]. Shift
amounts 32 and 63 were already handled.
New testing for shift amts 33 and 62 added in sra.ll. Changes to other
test files were to adapt previous test results to this extension.
