commit 5da580beacb0da1f7bf8e300e074e5cad88b8bbc
Author: Simon Peyton Jones <simonpj at microsoft.com>

Performance improvement of the compiler itself
This is a result of one of these, or a combination
002b7a2b * Give the worker for an INLINABLE function a suitably-phased Activation
ca666b8b * When finding loop breakers, distinguish INLINE from INLINEABLE
a98c9c5e * Fix a bug in CSE, for INLINE/INLNEABLE things
Some changes are quite big: for bytes_allocated we have
T6048: 13% below expected
T5837: 15% below expected
T3064: 5% below expected
Of course, these might have already been close to their lower
threshold, so perhaps not all the improvement is from here.
But it is good news all the same.
