existing code that updates LiveVariables is fairly slow as it is.
There isn't a command-line option for enabling this; instead, just edit
PHIElimination.cpp to require LiveIntervals.

Parse the attribute group reference on a function.
Attribute references are of this form:
define void @foo() #0 #1 #2 { ... }
Parse them for function attributes. If there's more than one reference, then
they are merged together.

When Mips16 frames grow large, the immediate field may exceed the maximum
allowed size for the instruction. This code uses RegScavenger to fix this.
We sometimes need 2 registers for Mips16 so we must handle things
differently than how register scavenger is normally used.
