builtins: Select correct code fragments when compiling for Thumb1/Thum2/ARM ISA.
Summary:
Value of __ARM_ARCH_ISA_THUMB isn't based on the actual compilation
mode (-mthumb, -marm), it reflect's capability of given CPU.
Due to this:
- use __tbumb__ and __thumb2__ insteand of __ARM_ARCH_ISA_THUMB
- use '.thumb' directive consistently in all affected files
- decorate all thumb functions using
DEFINE_COMPILERRT_THUMB_FUNCTION()
---------
Note: This patch doesn't fix broken Thumb1 variant of __udivsi3 !
