[ARM] Merging 64-bit divmod lib calls into one
When div+rem calls on the same arguments are found, the ARM back-end merges the
two calls into one __aeabi_divmod call for up to 32-bits values. However,
for 64-bit values, which also have a lib call (__aeabi_ldivmod), it wasn't
merging the calls, and thus calling ldivmod twice and spilling the temporary
results, which generated pretty bad code.
This patch legalises 64-bit lib calls for divmod, so that now all the spilling
and the second call are gone. It also relaxes the DivRem combiner a bit on the
legal type check, since it was already checking for isLegalOrCustom on every
value, so the extra check for isTypeLegal was redundant.

[Coverage] Fix the start/end locations of switch statements
While pushing switch statements onto the region stack we neglected to
specify their start/end locations. This results in a crash (PR26825) if
we end up in nested macro expansions without enough information to
handle the relevant file exits.
I added a test in switchmacro.c and fixed up a bunch of incorrect CHECK
lines that specify strange end locations for switches.

[ELF] Generalize symbol type handling.
SymbolBody constructor and friends take isFunc and isTLS boolean arguments.
ELF symbols have already a type so than be easily passed as argument.
If we want to support another type, this scheme is not good enough, that is,
the current code logic would require passing another `bool isObject` around.
Up to two argument, this stretching exercise was a little bit goofy but
still acceptable, but with more types to support, is just too much, IMHO.
Change the code so that the type is passed instead.

CodeGen: Tune the SmallVector size in LiveRange
The vast majority of LiveRanges (ie, 4/5) have exactly 1 segment and 1

allocating space for 4 is wasteful. This is especially noticeable when
dealing with a very large number of vregs, and I have an internal case
where dropping this to 2 shaves over 5% off of peak memory when
