As I was finishing d98a4de718d9, it became evident that fsave
proliferation was becoming a problem. Especially considering tests,
there was much duplicated conversion code. This ties everything up
together in a central location.
test::BytesToHexString() is a new function to ease testing of byte
arrays like x87 registers, without having to loop over each byte.
Some static_asserts are added to verify that complex structures that
need to maintain interoperability don’t grow or shrink. This is used
to check the size of the fxsave and fsave structures, as well as the
MinidumpCPUContext* structures.

When no SSE (fxsave) context is available but x87 (fsave) context is, use the
x87 context.
This also embeds the x87 FPU opcode from the fxsave fop field in bits 16-26 of
the fsave error_selector field, true to the layout of the fsave structure. See
Intel SDM volume 1 (253665-061) 8.1.10 and figure 8-9.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.

Removes the bitness-specific targets in favour of pulling binaries from
the other build directory. This is to avoid the added complexity of
duplicating all the targets for the x86 in x64 build.
Overall, mostly templatizing more functions to support the
wow64-flavoured structures. The only additional functionality required
is reading the x86 TEB that's chained from the x64 TEB when running
as WOW64.
The crashing child test was switched to a manual CreateProcess because
it needs to launch a binary other than itself.

A few function implementations that were missing, various switches
for functions/functionality that didn't exist on XP, and far too long
figuring out what exactly was wrong with SYSTEM_PROCESS_INFORMATION
on x86 (the "alignment_for_x86" fields).
