e572809aa1 Extend global merge pass to optionally consider global constant variables.
Also add some checks to not merge globals used within landing pad instructions or marked as "used".

c8888c7d80 XFAIL for all. These tests are darwin specific anyway.

53dc40a45f Disable ARMGlobalMerge on darwin. The debugger is not yet able to extract individual variable's info from merged global.

619a372617 Fix ARMGlobalMerge pass to check if globals are entirely within range.
It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

72831dc905 Change the symbol for merged globals from "merged" to "_MergedGlobals".
This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

edf046716c Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes.
It was mistakenly looking at the pointer type when checking for the size of
global variables.  This is a partial fix for Radar 8673120.
