(a) keep 32-bit as the default

FYI, Wayne is working on getting us numbers, and will try to send them
later. Thanks in advance!

(Based on his initial queries, it seems there are still a considerable
amount of users on 32-bit only Windows platforms.)

Indeed, there is a sizable set 32-bit Windows users.  The following is likely a fair estimate of our WINDOWS user population via crash statistics.   The numbers are percentage of users, and virtual memory size of the Thunderbird process.

All Thunderbird versions, all Windows versions

85.61 %  4294836224              32bit Thunderbird running in 64bit Windows
12.44 %  2147352576              32bit Thunderbird  running in 32bit Windows or 64bit Windows configured to run TB in 32bit mode
  1.43 %  140737488224256   64bit Thunderbird running in 64bit Windows

The subset of XP users is  0.07 %  or XP 5.1.2600 Service Pack 3

Windows 10 users only

93.44 %  4294836224                32bit Thunderbird running in 64bit Windows
   4.11 %  2147352576   **         32bit Thunderbird  running in 32bit Windows or 64bit Windows configured to run TB in 32bit mode
   2.30 %  140737488224256     64bit Thunderbird running in 64bit Windows

** yes, there are people running Windows 10 in 32bit mode

Windows 7 users only

74.05 %  4294836224 38160
24.77 %  2147352576 12763

Would it be possible to pack both the 32-bit and 64-bit binaries into the installer, and automatically install the correct ones for the platform?  Alternatively, maybe use an online installer like Firefox does that grabs the correct installer for the system?
