ix86_maybe_switch_abi is called to late during RTL expansion and we
use the stale information from compilation of the previous function.
aggregate_value_p uses call_used_regs. aggregate_value_p is used by
IPA and return value optimization, which are called before
ix86_maybe_switch_abi is called. This patch merges ix86_maybe_switch_abi
with ix86_set_current_function.

We have a global 1/2 and a cached 1/3, but recalculate 1/4, 1/6 and 1/9
each time we need them. That seems a bit arbitrary and makes the folding
code more noisy (especially once it's moved to match.pd).
This patch caches the other three constants too. Bootstrapped &
regression-tested on x86_64-linux-gnu.

This patch introduces the Package_alias class which is a
finer representation of the different between a package and the
aliases it is imported under. Each alias keeps track of the location
of its import statement and how many times that alias has been used.
This allows the gofrontend to report when a specific import has not
been used even if a symbol from the package has been used by another
import.
Fixesgolang/go#12326.

Analyze only those bbs which are outside the region for uses which might be
defined inside the region. This is intended to improve the compile time. This
algorithm may be further improved by only looking at the successors of region as
these regions are sese. Added FIXMEs to make this improvement in future.
Passes regtest and bootstrap on x86_64.
