Make fixed-abi default for AMD HSA OS

[madhur13490]

Summary

fixed-abi uses pre-defined and predictable
SGPR/VGPRs for passing arguments. This patch makes
this scheme default when HSA OS is specified in triple.

386–388

This isn't just changing the default, this is breaking the flag. You should check if the option wasn't specified

rebase, address Matt's comments

You should keep the two checks with the flag on and off

[madhur13490]

Keep both flags

This test should force use the variable ABI. We already have a dedicated test for the fixed ABI for these inputs (callee-special-input-sgprs-fixed-abi.ll)

[madhur13490]

force varabi on callee-special-input-sgprs.ll

Setting this 'true' on everything is expected to be a regression. Specifically any code that uses functions, but doesn't use indirect functions, is expected to be slower than it was before. Suggest reverting this patch.

Alternative would look something like:

• if there is any indirect call, set this true
• otherwise, leave it unchanged

That will fix things using indirect calls without regressing everything else.

note: llvm::Function::hasAddressTaken() looks useful for that
