SUMMARY:
The patch detects MIPS application specific extensions (ASE) like micromips by reading
ELF header.e_flags and SHT_MIPS_ABIFLAGS section. MIPS triple does not contain ASE
information like micromips, mips16, DSP, MSA etc. These can be read from header.e_flags
or SHT_MIPS_ABIFLAGS section.

SUMMARY:
This patch implements
1. Emulation of MIPS32 branch instructions
2. Enable single-stepping for MIPS32 instructions
3. Correction in emulation of MIPS64 branch instructions with delay slot
4. Adjust breakpoint address when breakpoint is hit in a forbidden slot of compact branch instruction
