[PATCH] D28566: Disable Callee Saved Registers

[Oren Ben Simhon via Phabricator via llvm-commits]

oren_ben_simhon updated this revision to Diff 88546.

Implemented comments posted until 2/14 (Thank You Matthias & Quentin).

The main difference from last revision is that i moved the allocation and calculation of the updates CSR list.
The calculation will be performed every time a register is disabled and not when the list is requested.
This way we don't need a const cast when retrieving the CSR list.
